/**
 * An adapter class that allows using the TFT_eSPI library as if it was an OLEDDisplay implementation.
 *
 * Remaining TODO:
 * optimize display() to only draw changed pixels (see other OLED subclasses for examples)
 * Use the fast NRF52 SPI API rather than the slow standard arduino version
 *
 * turn radio back on - currently with both on spi bus is fucked? or are we leaving chip select asserted?
