Added new board: M5Stack DinMeter (esp32s3)

[juergenpabel]

I've added a new board: M5Stack DinMeter

The compiled firmware was tested in the context of an ongoing project of mine and appears fully functional.

Explicitly tested hardware-features that work:

• Display
• Rotary & Button
• Bluetooth LE
• Grove Ports A & B (albeit only GPIO functionality was tested)
  I didn't test WIFI, Grove I2C and power-management - but as those aren't board specific features, I expect for them to work just as well.

As a side note: I didn't know whether a new board is considered as something that should be targeted for the current release-branch (10.0.0 as of just yesterday) or onto the main branch. Maybe this could be added as an additional guidance to https://learn.adafruit.com/how-to-add-a-new-board-to-circuitpython/submit-a-pull-request

OK, the duplicate USB VID/PID check fails - what would the appropriate PID for this board be?

Thanks for the board def! You can request a PID here: https://github.com/espressif/usb-pids

I've added an alert to that page about branches and a note on the getting setup page. Right now main is essentially 10.0.x so this is to the best branch. We have 9.2.x as well but won't likely release to it anymore.
