Copy Python3 code to Python2 lib

Python2:
- Added author
- Added Sensor class
- Added HomeSFR class
- Corrected date error for cameras (datetime.datetime.strptime does not understand '0000-00-00 00:00:00')
- Added encoding error TODO

Python3:
- Changed __name__
- Remove import of datetime.timezone
- Corrected date error for cameras (datetime.datetime.strptime does not understand '0000-00-00 00:00:00')
