Fast bit-banging from ESP32 to ILI9341 TFT LCD screen.

I got a cheap TFT shield, with touch capability (under USD $7) from Banggood. So I set myself a target of 25 frames per second sending to the 320x240x16-bit per pixel. (Nothing useful yet, just changing all the pixels to a new colour). I got above 40 fps eventually, so a bit better than 6MB (48Mb) per second from my ESP32. I used what I thought was a nice trick with some tables for the bit-banging.
