vedo - 2022.4.1

This version includes various fixes, but the most important thing is that it implements the snake_case naming scheme (instead of camelCase) for all class methods and functions, so e.g. code like this (in vedo==2022.3.1): python mesh = Mesh("bunny.obj") mesh.cutWithPlane() now becomes (in vedo==2022.4.1): python mesh = Mesh("bunny.obj") mesh.cut_with_plane() ##### <---- Check out the docs in case of doubts.
