Arduino code for drawing BMP images from LittleFS to Waveshare 7.3 inch 7 color epaper (F) display using an ESP32

It is highly recommended to use 4-bit BMP as these already have a large file size (190 kB for 800x480).
Lower size images are supported, make sure height and width are both an even pixel count.

Set pins in epdif.h. Use another program, e.g. WLED, to upload BMP images to LittleFS filesystem.
Early demo stage, I am not fully satisfied with the performance of this display as of now as there is a loss of contrast and striping when drawing dithered photos.

Code is based on the official demo by Waveshare
