This PR adds a new example, v4l2py-snapshot.py. It's implemented as a command line tool, allowing to take a snapshot from a V4L2 device and save it to disc as .jpeg. In case Pillow is available, some additional postprocessing features become available, such as rotating or flipping the image before it is saved to disc.
improve_controls+config+snapshot has been branched off of improve_controls+config, which contains the code referenced in PR #43 that is now also contained here. This PR will shrink to the difference between improve_controls+config and improve_controls+config+snapshot once PR #43 is merged. The code for this example starts with 546c98.
Please let me know if you have any questions, suggestions or would like to see any changes to the code to have it merged.
