PyMap3D - Bugfix: don't use numpy.seterr

use warnings.catch_warnings() context manager instead of numpy.seterr to avoid breaking other programs that import pymap3d and want their warnings not to be errors.

Thanks @sanguinariojoe for the report and suggested fix

PyMap3D - overhaul Ellipsoid, fix Numpy warning to error

Numpy would issue warnings that could cause incorrect computations by not being caught in try: except: for things like divide by zero. This has been fixed.
overhaul the Ellipsoid() class
apply good coding style and use only pyproject.toml (no setup.py, setup.cfg)
Require Python >= 3.8: Numpy NEP29 dropped support for Python < 3.8 in December 2021. We are having a harder time supporting corner cases in Python 3.7.

PyMap3D - remove most numeric type hint

The type hinting for most numerics was removed to avoid causing external package problems as per #50. thanks @randallpittman The CI coverage was improved by testing each supported Python version across MacOS, Linux, and Windows. The PEP621 pyproject.toml meta was removed to avoid duplication and conflicts with setup.cfg. thanks @philblckwd

PyMap3D - speed imports, add -m pymap3d.{vdist,reckon}

Don't automatically import less widespread used modules including: lox los rcurve rsphere` this speeds imports for most users.

add command line convenience functions:

```sh python -m pymap3d.vdist python -m pymap3d.vreckon

```

PyMap3D - bugfix: ecef2geodetic inside bug from 2.6.0

PyMap3D - 100x speedup for Numpy operations

eliminated numpy.vectorize for ~100x speedup of many of the pymap3d functions, while still preserving the "no-Numpy" functionality for scalars.

PyMap3D - Python >= 3.7, modernize type annotations

For better internal quality, modernize type annotations in accord with Numpy 1.20 final release. This requires __future__.annotations, which requires Python >= 3.7. For many months, Python 3.5 use of pymap3d has been ≪ 1% Python 3.6 use of pymap3d continues to drop as current Numpy requires Python >= 3.7 as well.

Python 3.5 and 3.6 users can continue to use pymap3d 2.4.x. If we find any significant bugs, we plan to backport them to pymap3d 2.4.x as long as there is still significant pymap3d usage from Python < 3.7.

PyMap3D - prepare for optional Numpy 1.20 type hinting

Numpy 1.20 adds optional type hinting in the numpy.typing module. ArrayLike is a key type we feel appropriate for PyMap3D. PyMap3D will continue to work without Numpy or older versions of Numpy.

We add optional type hinting using numpy.typing.ArrayLike

PyMap3D - ECI: restore less accurate Numpy-only fallback

v2.4.0 too boldly removed the non-AstroPy ECI conversions that only require Numpy. However, the Numpy-only fallback can have several percent error due to rotation only being considered. AstroPy considers higher-order effects that greatly increase accuracy of conversions involving ECI (eci2* or *2eci)

This release restores optional status of AstroPy for ECI, but Numpy is still required for ECI as it always has been for PyMap3d.

PyMap3D - eci: use AstroPy

The ECI calculation error was substantial for some applications due to only considering Earth rotation. Now ECI calculations use AstroPy for better accuracy (< 1% error) considering more factors in the ECI transformations. Fixes #33

Added geodetic2eci

Added more ECI self-tests

Temporarily pinned CI to Python 3.8 to avoid the usual issues with brand new Python releases not immediately having PyPi wheels for Astropy. We still also test Python 3.5.

PyMap3D - return scalar for scalar input

v2.0 introduced the use of numpy.vectorize to allow seamless pymap3d use with ndarray but also without numpy and scalars. However, this returned 0-d ndarray for certain functions rather than scalars for scalar inputs. This fixes that issue and adds tests for it.

PyMap3D - add geod2geoc, geoc2geod

API change: the last releases geodetic2geocentric and geocentric2geodetic have a "alt_m" parameter now. Set it to zero to act like before / Matlab. include the altitude to account for object height above ellipsoid.

Type hinting / quality / refactoring

Added diagnostic plots

Corrected / updated docs and error messages.

PyMap3D - add numerous geodetic / spherical transforms from @rpavlick

Thanks to @rpavlick for adding numerous functions in rcurve, rsphere, latitude, lox, utils and more. These functions each had tests written. Further, some Numpy functionality that was accidentally removed from v2.0 was restored for v2.1.

The goal of the PyMap3D package remains to support non-Numpy users, while also fully supporting those who have Numpy. The non-Numpy users are typically robots or platforms that stream positions in realtime, and don't need arrays, and want the faster performance of Python's built-in math module.

PyMap3D - Drop Python 2.x, improve numerical stability, improve non-Numpy use, move to GitHub Actions CI

Drop Python 2.x as code duplication and maintenance burden is too high.
improve numerical stability, thanks @bcminch #27
make non-Numpy use a first-class use case, with all but ECI working without Numpy (let us know if non-Numpy ECI is desirable). Of course Numpy, Pandas and Xarray are still handled first-class as well.
move CI to GitHub Actions.

PyMap3D - Enable fallback to Python 2.6, 2.7 and 3.4

Full functionality of PyMap3D (as with Python in general in 2019) requires Python ≥ 3.5, but a useful subset is made available to Python 2.6, 2.7 and 3.4. This is relevant to MicroPython and ROS users and other special use cases where currently supported Python versions may not yet be readily available.

Put Ellipsoid() in its own file for clarity and flexibility with other packages.

ECI functions previously had an API unlike other PyMap3D functions, they are now the same as the rest of PyMap3D (scalar or N-D array for each variable).

Also handles ecef2geodetic scalar input.

PyMap3D - BUGFIX: aer2geogetic ellipsoid specifier

AER2GEODETIC was always going to the default WGS84 ellipsoid since the ell= argument was not present. We have fixed this error.

Also did a complete rewrite of documentation to numpydoc standards (mostly) and regenerated with pdoc3.

PyMap3D - BUGFIX: ecef2geodetic negative altitude

Corrected algorithmic error for ecef2geodetic where negative altitude wrapped to positive altitude

PyMap3D - pdoc docs, negative altitude OK

use pdoc instead of sphinx for autogen docs

Don't limit altitude to be positive in geodetic2ecef, useful for near-earth WGS84 not exactly matching Earth's complicated surface.
