M5Paper support

**Describe the problem you have/What new integration you would like**

I've got my hands on the M5Paper from M5Stack and would love to use the e-ink touch display to render switches and buttons that communicate with HomeAssistant through ESPHome. I have no idea if this is the correct place to put this request, as I'm fairly new to programming micro controllers.


**Please describe your use case for this integration and alternatives you've tried:**

I've searched the documentation of ESPHome to find a way to interacht with the touch screen and e-ink display of the M5Paper, but I could not find something useful or something that worked. It might be my own shortcoming, as I do not have that much experience with ESPHome or ESP32 in general.

**Additional context**

It might be noteworthy that M5 already has their own library [M5EDP](https://github.com/m5stack/M5EPD) to do basic stuff with the M5Paper. This might be a starting point? The link to the Github M5EPD project also contains a bit more information about the device and the hardware configuration.

Start by reading the M5EPD library linked in the issue and its information about the M5Paper hardware. No ESPHome files, entry points, or tests are named, so the implementation scope needs investigation first. Done would mean usable touch-screen and e-ink display support for communicating switches and buttons with Home Assistant through ESPHome.
