Fast driver for IPS 240x240 ST7789 display

[devbis]

Hi everyone,

Some time ago I presented my driver for the IPS driver from AliExpress (viewtopic.php?f=15&t=5969).
It was written in Python and its performance was deficient.
So I rewrote this driver in pure C, and the performance of the screen increased significantly (35 times faster drawing a line)

I checked the driver on ESP8266 and ESP32 controllers.
Feel free to use it.

Nice work! I definitely think it makes sense having data intensive libraries, especially display drivers, written in pure C.
I have a bunch if libraries that could benefit from the same optimisation.
