Green color in grayscale problem

[gtwht]

Hello.

I found a problem with displaying colors for st7789. this problem is described here: https://forum.arduino.cc/t/problem-with-st7789v-displays-green-value-1-and-every-other-uneven-is-gray/700584/13

My solution was to add these lines in Panel_ST7789.hpp :

static constexpr uint8_t CMD_RAMCTRL = 0xB0;
CMD_RAMCTRL, 2, 0x00, 0xF0, //0xC0

Hello, @gtwht
Thanks for bringing this information to my attention !
I was totally unaware of this.
I have checked the configuration and confirmed that it works, so I have reflected it in the develop branch.
