I've accidentally implemented a reasonable chunk of a driver for the MMC5983 magnometer (I have a Sparkfun Micro Magnometer (Qwiic)), and I wanted to check if:

1. This would be useful to anyone else
2. This is being worked on by anyone else

I'll likely polish up what I have and open a PR in spare time over the next week or two — please let me know if it's already being developed elsewhere!

(I'm slowly working my way through the Qwiic/StemmaQT boards I own and documenting them on #739)
