fix(sensors_plus)!: Use magnetometer instead of deviceMotion

[tlserver]

Description

As #2248 said:

In previous version, FPPMagnetometerStreamHandlerPlus use deviceMotion instead of magnetometer to allow iOS present calibration interaction. So, in iOS, userAccelerometerEventStream and magnetometerEventStream share the same sampling period. In android, they have their own sampling period.

So this PR use magnetometer instead of deviceMotion. but this is a BREAKING CHANGE!!
