Bodmer 3f19788c93 Minor performance boost for ILI9488 
ILI9488 displays have become more available and more library users are using the SPI version.

An option to use a bidirectional MOSI pin with ESP32 has been added, so SDO can be left disconnected. See #898

Bodmer 22c514cce9 #940 - Extend allowed TFT_WR pin allocation for ESP32 
TFT_WR is 8 bit parallel mode can now be allocated to GPIO >31
Note: allocating a GPIO higher than 31 has a small perfomance impact (~1.23x slower) since signle register write with the data mask cannot be performed.

ESP32 DMA will hold TFT_CS low automatically.
STM32 will not do this and requires bracketing DMA transfers with startWrite and endWrite as in examples.

// Note: The following sprite to sprite colour depths are currently supported:
//    Source    Destination
//    16bpp  -> 16bpp
//    16bpp  ->  8bpp
//     8bpp  ->  8bpp
