Change imu to fifo mode

[mkamalel]

Implemented FIFO in IMU and integrated it with data queue. Future improvement could be to send the data in bulk into the queue and insert it into the database in bulk

I think its good to keep it in its own directory, makes the relation between the adafruit library and the imu controller clear, in the future it might be good to have a sensor directory with all the drivers for each device
