Support for micro:bit 2.21

[tiny2tm]

Hi
I have just received 5 micro:bit 2.21 devices.

They are unfortunately not supported in bluing.
Uploading the file in /usr/local/lib/python3.10/dist-packages/bluing/res/micro-bit.hex results in:

error: The application image is not compatible with the target.
type: user

What will it take to support this?
Can someone point me in the right direction generating a new hex file for version 2.21?

Br.
Søren
