feat: add lilygo t5 e-paper support

[pyaillet]

Hi!

Thank you for making mousefood :)

Here is a PR to add support for lilygo T5 e-paper.
I am not sure about the color mapping part, for the rest I mainly followed what was done for other e-ink display.

I wanted to follow the PR template but was not able to find it.

Looks good, thanks for the PR! I just added some comments.

Also, do you mind updating the top-level README.md about this?
It would be great to also tackle #170 (e.g. #171)

Btw have you tried rendering anything more impressive than a block and text on the screen? I'm just curious about how it might look and possible limitations.

We should also update CI for checking whether the example compiles :)

[pyaillet]

I gave a shot at adding the CI for the new example.

It's a bit tricky, because of the lilygo-epd47 driver being tied to the esp32s3 microcontroller.
Then compiling with all-features pulls the need to compile with the espressif fork rather than the default toolchain which does not know about xtensa.

I will try to figure a way to solve this, but any idea is welcome :)

[pyaillet]

In fact, I realize it's even worst than what I thought, it's not the example compilation that fails but the whole project build with all-features.
I need to find a way to fix this.

I reworked the dependencies to make it work.

LGTM, thanks!
