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.

Fix rounding issues of times for ADwin: Added a PseudoclockDevice for each TiCo, which fixes using the wrong resolution in 'Device.quantise_to_pseudoclock'; overwrite 'collect_change_times' for TiCo, becuase floating point errors triggered errors during checkes of time deltas.

This will make the changes easier, in case the repository is named differently.
Then one only needs to change the path in register_classes.py.

The default PID limits should not be (-10,10), but those specified in
the Output class, to ensure staying in safe limits.
Small fix, if PID channel is set with integer number.

Added adapted class for AnalogOutput with PID control.
This avoids having extra Widgets in the ADwin BLACS Tab,
the PID parameters can be set also in manual mode and the number
of AOut channels with PID is not fixed.

MISSING: Sending data to the right ADwin variables in the Worker and
adapting the ADwin process (to also set PID parameters).

Now the gain of the input set for a PID is considered, such that the set value is the physical voltage that goes into the ADwin.
For that I also changed how we keep track of the AIn of PID channel index for the module arrays (moved storage from Attributes in devices to connection_table_properties).

Because the TiCo is started later than the Adwin main process,
an error is raised if we want to change the output too early again after t=0
