/*!
@brief An optional adjunct to Adafruit_EPD that reads RGB BMP
images (maybe others in the future) from a flash filesystem
(SD card or SPI/QSPI flash). It's purposefully been made an
entirely separate class (rather than part of SPITFT or GFX
classes) so that Arduino code that uses GFX or SPITFT *without*
image loading does not need to incur the RAM overhead and
additional dependencies of the Adafruit_SPIFlash library by
its mere inclusion. The syntaxes can therefore be a bit
bizarre (passing display object as an argument), see examples
for use.
