feat: add mpu-6000 example

[genan2003]

Pull Request Overview

This pull request adds an example for MPU-6000 sensor.

According to the datasheet the sensor differs from the MPU-6500 in the following way:

• The default value of WHO_AM_I register is 0x68 rather than 0x70 for the MPU-6500
• The MPU-6000 requires SPI Mode 3 (CPOL=1, CPHA=1) in order to work
• We have to disable the I2C interface, since the sensor will be used with the SPI interface
• To begin reading we must set the register PWR_MGMT_1 we must clear the SLEEP bit

The readings from the sensor are computed the same as before, so is just extra configuration of the device.

TODO or Help Wanted
