Compatibility with SSD1683

[AJMansfield]

I'm trying to use an HINK-E042A88 display, connected via an Adafruit eInk Feather Friend to my Adafruit Feather RP2040.

The datasheet for this display notes it uses an SSD1683 drive IC, and gives a breakdown of some of its commands. Other documentation I've found for the SSD1683 gives a more complete picture, with only very minor differences to the SSD1681 documentation I've found.

As far as I can tell, there are only two commands present on the SSD1683 that are not present (or at least, not documented as present) on the SSD1681:

Code	SSD1681	SSD1683
0x16	n/a	Program WS password to OTP
0x17	n/a	Program Automated

All other commands are the same, and use the same argument formats. I've tested using the ssd1681.py driver for this display and it does appear to work correctly, except for a technical issue I've discovered that would also theoretically impact larger SSD1681 displays:

• ssd1681: Fix OverflowError for displays larger than 255x255. #90

I've found better documentation for the SSD1683; it seems the document I had, specific to the particular display mine is attached to, was woefully incomplete.

Based on my tests, it seems that the exisiting driver is compatible and can be documented as such: you can just treat an SSD1683 display as if it were an SSD1681 display when using it with this library.
