picam hardware trigger failing. #245

The picam hardware trigger works fine for snaps and live but fails in experiment. I wonder if the trigger pulses are just too short for the Pi.

Tesated extensively, with a pi 4 and picamera v1.3 100us pulses are able to trigger images reliably. The readout time is slow and currently set to 0.7 s. The frame rate setting also influences the exposure time possible so this took a bit of work to get correct (#286). I think it is now all working correctly.
