Crappy 2.0.2

This new release of Crappy brings improvements mostly on three aspects of the module :

It moves most of the packaging metadata from setup.py to pyproject.toml (#68). This paves the way for a complete removal of the setup.py file, once all the extension modules are removed from Crappy in version 2.1.0 (#62).
It brings a final touch to the documentation (collapse menus, section authors, intersphinx mapping, changesets), already entirely refactored in #79.
It comes with substantial improvements on the existing Camera classes, in terms of implemented settings and functionalities. Only the RaspberryPiCamera remains to improve, in #64. The improved cameras are:
- The XiAPI Camera, with more settings to tune and bug fixes.
- The CameraGstreamer Camera, with a better support when v4l-utils is not installed and more parameters to tune when v4l-utils is installed.
- The CameraOpencv Camera, with more parameters to tune when v4l-utils is installed.
Also, a few minor bug fixes
