TTGO-WATCH-2020 display support

[cr0mbly]

Reading the docs it looks like the ST7789V display for this watch should work, I've tested this based on the PIN out provided from the source but can't seem to make it work, any ideas?

from display import TFT

tft = TFT()
tft.init(tft.ST7789, backl_pin=12, miso=0, mosi=19, clk=18, cs=5, dc=27, backl_on=1)

on execution of the above I can't interface with the display, the backlight doesn't event turn on.

I ended up finding a helpful example that got this going using an alternative firmware, here's an example, for anyone looking in the future.
