* change LSM6DS3TR(-c) gyroscope and accelerometer to interrupt
* add pthread for linking
* add interrupt collector thread to fetch in parallel to non interrupt based sensors
* change get_event interface to return true on successful read
* fetch sensor interrupts via gpiochip
* avoid sending empty messages (interrupt only, non interupt magn can leave a gap in the orphan block)
* add verifier script to sensor interrupts (sensor_data_to_hist.py)
* add/update sensord testsweet (test_sensord.py)
* add poll timed out check
* unexport interrupt gpio pins
* gpiochip on both edges, but skip falling edge if rising edge is detected, this is handled in the sensor as the status flag is checked if new data is availble
* add test to sensord to verify 100Hz interrupt frequency
* add sensor shutdown/low power mode functionality on sensord exit
* relax test, will be readded in the splitup PR
