Add optional trigger support to sample. If the selected temperature sensor supports triggering using the AMBIENT_TEMP channel, then temperature thresholds will be set for +0.5 and +1.5 degrees celsius above ambient temperature. Sample overlays are provided for the FRDM_K22F board to demonstrate enabling this feature. Signed-off-by: Daniel DeGrasse <daniel@degrasse.com>
