add support for weact eink (2.13 maybe 2.9)

would be nice to add support for weact eink module...
https://github.com/WeActStudio/WeActStudio.EpaperModule

I have already played with it and is almost working... with this

```
57 spi:
58 id: bus_a
59 clk_pin: GPIO04
60 mosi_pin: GPIO06
61 miso_pin: GPIO05

71 display:
72 - platform: waveshare_epaper
73 spi_id: bus_a
74 model: "2.13in-ttgo-dke"
75 reset_pin: GPIO02
76 cs_pin: GPIO07
77 dc_pin: GPIO01
78 busy_pin: GPIO3
79 rotation: 90
80 full_update_every: 60
81 update_interval: 120s
```
on an esp32-c3 also tested on a normal esp32 nodemcu

the only issue I noticed is the bottom row is full of noise.. I traced this to the fact the ram on x somehow is shifted. starts at 0x01 but shall start at 0x0 the size is correct...

Start with the existing waveshare_epaper platform and the WeActStudio.EpaperModule documentation linked in the issue. Reproduce the supplied ESP32 configuration for the 2.13-inch module and investigate the reported bottom-row noise caused by the RAM address starting at 0x01. Done means the WeAct module is supported without the shifted-row artifact.
