…le_dmp_sensor_int work

This commit makes inv_icm20948_enable_dmp_sensor and inv_icm20948_enable_dmp_sensor_int more like the InvenSense example.
_enabled_Android_0/1 and _enabled_Android_intr_0/1 keep track of which sensors/interrupts are enabled, so that more than one sensor can be enabled. Sensors can now be disabled too if required.
Adding ICM_20948_Stat_FIFOIncompleteData as a return value for inv_icm20948_read_dmp_data.

Adding support for ZaneL's Node.js Quaternion animation tool:
