d0918826de* 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
