Implement YarpParametersHandler bindings

[GiulioRomualdi]

This PR implements the python bindings for the YarpParametersHandler class.

It is possible to load the parameters directly from the configuration file thanks to set_from_file method. While writing the tests I noticed a bug in the setParameter method for the YarpParametersHandler #308. I think this is te reason why the test is failing:

Overall the PR looks good to me 👍 I didn't catch anything off.

#311 should fix the error in the tests

[GiulioRomualdi]

#313 should fix the last bug

[GiulioRomualdi]

CI failure is now related to librealsense IntelRealSense/librealsense#9102
