Add e-paper display GDEW0213T5 (LilyGo T5 v2.3.1)

**Describe the problem you have/What new integration you would like**
LilyGo have a number of different T5 2.13" e-paper displays. I have just got one with a GDEW0213T5 display - https://lilygo.cc/products/t5-2-13inch-e-paper?_pos=1&_sid=78fbb3a6d&_ss=r

It looks to be a Good Display panel - https://www.good-display.com/product/229.html

**Please describe your use case for this integration and alternatives you've tried:**
I've tried various of the models listed at https://esphome.io/components/display/waveshare_epaper.html, including all of the `2.13in-ttgo-` ones -none of these work.

`gdew029t5` does work (for a very basic hello world) - however the size is wrong as GDEW029T5 is 2.9" / 128x296 rather than 2.13" / 104x212 for the GDEW0213T5.

**Additional context**
I don't know if the only difference between the GDEW029T5 and GDEW0213T5 is the size. The panel is supported in https://github.com/ZinggJM/GxEPD2, which I've seen referenced to in various posts about other e-paper displays.
