MicrobitV2 get LED brightness returns wrong values

[heini208]

Describe the bug

• The get LED brightness block does not return values ranging from 0-9.
• Instead it returns doubling values till 256 (0,1,2,4,8,16,32,64,128,256)
• This bug is not reproducible in the python editor by microbit. This most likely means that this issue would get resolved by updating the firmware hex used to generate the hex file in the lab.

To Reproduce Steps to reproduce the behavior:

1. Go to microbit v2
2. Go to the expert toolbox
3. Set the LED brightness to a value greater than 2
4. Read the LED brightness via the display or serial
5. See Error

Expected behavior

• The get LED brightness block should return values from 0-9 that match the value set in the set LED brightness block.

Additional context

• This should also be tested on the original microbit.
