Added SD card storage for smooth fonts with ESP32
ESP32 will use PSRAM (if available and enabled) to hold smooth font
metrics
Improve performance of ESP32 Sprite shared functions
Add basic ST7789 driver option
Latent bug fixes for pin mask
// For ST7789 ONLY, define the colour order IF the blue and red are
swapped on your display
//#define TFT_RGB_ORDER TFT_RGB // Colour order Red-Green-Blue
//#define TFT_RGB_ORDER TFT_BGR // Colour order Blue-Green-Red
The library supported 240x240 ST7789 displays only which require an 80
pixel offset in rotation 2 and 3
The library now also supports the 240x320 display which has a different
RGB colour order.
