Adjusting PaperTTY to work with weAct 2.9 about papertty HOT 6 OPEN

I don't have an epd2in9v2, so this is currently untested, but I took a stab at porting the waveshare driver over.
You can try it out here: https://github.com/mcarr823/PaperTTY/tree/epd2in9v2

@Uri0533 I think it probably can be made to run faster, but it's hard to say without a device to test with.
Right now the code is written more or less the same as the code from Waveshare with only minor modifications.
To potentially make it faster I'd start by tinkering with the display_partial function.
eg. Seeing if it works if the LUT is loaded only once instead of every time, or seeing if set_memory_area and set_memory_pointer can be changed to allow for partial writes.

Actually, it might just be the panel.

Interesting that the code for the epd2in13v4 works on the epd2in9v2 at all.
I guess the code is fairly similar. The main difference is the LUT loading.
You could try commenting out the calls to set_lut and see if it makes a difference.
