I kinda lost interest, after my 3d printer took a shit. however, I have gotten it working. |

How does the wakeup sequence work? It appears to write to read-only register 09H, and only under regular scan, not scan_ext |

This adds support for the QMC5883P, as well as the WHOAMI, as per my own research and the datasheet.
Sadly, I needed to modify the scan code to special case it, as it wasn't always detected when using it over the secondary I2C data lines of a IMU. It will sometimes work without it, but it isn't 100% reliable, so I feel it's better to have done so.
See the datasheet: https://www.qstcorp.com/upload/pdf/202202/%EF%BC%88%E5%B7%B2%E4%BC%A0%EF%BC%8913-52-19%20QMC5883P%20Datasheet%20Rev.C(1).pdf
I ended up modifying the BMI270 to clearly have the name, for clarity. I know this project does not support other BMI chips, but my personal fork may end up doing so. (even though a PR will never be made, so no one has to maintain it). If needed, I can revert it, but I see no harm.
The other thing I did was remove some miscellaneous whitespaces in some of the calibration and scan code.
From my previous PR, with more comments for clarity on why certain things were done.
