Add A22YYUV as a variant of A02YYUV ultrasonic sensor

[PhracturedBlue]

Component name

a02yyuv

Link to component documentation on our website

https://esphome.io/components/sensor/a02yyuw/

Describe the enhancement

DYP has a few variants of waterproof sensors that speak the same UART protocol, but use 115200bps instead of 9600.
I can get these working by simply duplicating the A02YYUV component and changing the 9600 to 115200 in the sensor.py code.

I can create a pull request, but I'm not sure what the recommended configuration should be. Should I just allow overriding the baud rate? or maybe add a new variant that changes the baud rate?

Use cases

There are other DYP ultrasonic waterproof sensors that could be supported with the same code using a minor change

Anything else?

I stumbled upon your request while looking into this myself. I actually wrote a custom component to handle various DYP UART sensors (including the A22, though I originally built it for the A13).

Your post prompted me to finally submit it as a Pull Request: esphome/esphome#12761

It is still a work in progress, but I wanted to drop the link here so you can follow the development.
