Acc/Gyro/Mag Sampling rates need updating for Sense rev2

[cal-armstrong]

Sampling rate data for the BMI270_BMM150 Library does not match latest version e.g. https://docs.arduino.cc/tutorials/nano-33-ble-sense-rev2/imu-accelerometer (see 'The BMI270_BMM150 Library') v's https://www.arduino.cc/reference/en/libraries/arduino_bmi270_bmm150/

Usage of library reveals data in second link to be correct (99.8 and 10Hz)
