transform into 4 bits/pixel and used on ESP8266/ESP32.I have tested it on
ESP32,both SPIFFS and flash array.
Main modifications :
- added support for loading and displaying 4-bit mode smooth font.
- added a tool made by pure C to convert font files.
The Smooth Font API is compatible with previous.Compressed font format is described in
tools/create_smooth_font/compress_font/readme.md
