[feature request] support for Sharp memory LCD

[Stefal]

Hi !
Following my question for menu management #112 I'd like to know if it's possible to support the Sharp memory LCD. These low power LCDs are a good solution when you want something readable under direct sunlight, without the e-ink drawback (slow refresh rate).
I plan to use this lcd on my bike for collection photos for OpenStreetMap contributions (you can see more here).

Sharp Memory LCD doc:

Some code on github:

Glancing at the datasheet, it appears to be an SPI device, so interfacing to it should be relatively straightforward. The sticking point to writing a driver is having one to test against though - are you able to source one for us ... either as a donation or a loan?

This ticket should probably be moved to the luma.lcd repo at some point.

@rm-hull I have an old one, from Adafruit. I will use it in the future, but in the meantime, I can send it to you. You're in the UK ? Give me your postal address and I will ship it.

@Stefal - sent a mail to your email address from one of your repo’s commits with my details. Let me know if it didn't arrive.

Closing - see linked issue: rm-hull/luma.lcd#61 - updates/progress will be posted there instead
