Reverts some of the install options from v1.0.1 so RPi dependencies are properly installed.

This version adds `rpi`, `fonts` and `extra-depends` extra to the library, so non-critical extras can be installed with `pip` like so:


pip3 install inky[rpi,fonts,extra-depends]


Or any variation therein- IE: a desktop user wanting to simulate an Inky display might do:


pip3 install inky[fonts,extra-depends]


* Enhancement: Tweak setup.py extras for easier dependency install
