Unify all Python trees for both RPi and Jetson Nano, Py2 and Py3

Browse source 
* Move lib files into waveshare_epd package
  * Use int() where integer division is needed
  * Use logging (debug level) in library files, so they can be used by a
    user script without print()s being output
  * Use logging (info level) in example files
  * Move Font.ttc file into pic directory
  * epdconfig.py: Detect RPi or Jetson Nano
  * Search for sysfs_software_spi.so in several places
  * Include both Jetson and RPi readme files
  * Include setup.py for package installation
  * Fix few small syntax errors preventing setuptools byte-compiling
