MPU6886::calibrateAccelGyro() failure

[mhaberler]

Hi, trying Calibrated_sensor_output.ino with an esp32 and an MPU6886

MPU6886::calibrateAccelGyro() fails to read back the FIFO sample count here - the readBytes() request is NAK'd, hence fifo_count is zero, resulting in a divide-by-zero here

not sure what to do about it, short from replacing gyro calibration with averaging

thanks! Michael
