ADwin: Implemented using multiple PID channels for one AnalogOut (than used to work, but we broke it with the last code changes where we split up PID init).

Added Fastcomtec MCS8A timetagger for measurements with SPCM

See merge request !5

Fastcomtec: Incresed wait times again, still don't know for sure what is the optimal (and most robust) delay

Fastcomtec: New device code to let MCS8A run for long time and save trigger signals instead of starting and stopping for each shot.

Changed default config for SPCM measurements: software start, 1.7s, highest binning, SPCM on channel 2.

PID improvements for ADwin

See merge request !4

Added limit check only when PID is off and set output when PID is turned off.

Adwin: Set PID gains and limits only once during init and not later when it's activated. Added extra dataset in shot file containing thise PID config.

Bugfix TimeBase: Removed "self.remote_values". So far when we set a value manually, the "smart_cache" was not updated, which casued the BLACS worker to belive wrongly that it still had the old value and did not reprogram when running the shot again. Just using self.smart_cache and helper function for returning frontpanel values.
