Detailed Description

Magnetometer operation-mode sweep for the DevLab ICM-20948.

Author: Jonathan Mejorado Lopez

Initializes the AK09916 magnetometer through the ICM-20948 internal I2C master, iterates through continuous measurement modes, and prints CSV-like magnetic field samples to the Serial monitor.
