Is it possible to expose Analog port 6 for checking battery?

[chino]

Based on [1] it appears that there is no way to check the battery level using makecode. From what I can see makecode getPin() [2] seems to check the bootloader config to see which pins are available. However we can see that A6 is not defined in the bootloader config [3]. I have provided an example makecode project [4] for testing as well.

I'm wondering if it would be as simple as exposing the mapping in the bootloader config for it to be available for use from makecode as well?
