The trigger mode selection should be sent to the device immediately when changed

[MarkRivers]

Currently the trigger mode selection is only sent to the device (SDK call) when acquisition is started. This is not good because switching triggers modes can enable detector scrubbing. If scrubbing is currently disabled and then a trigger mode that enables scrubbing is selected we want the scrubbing to be enabled immediately, not when acquisition is started. If not then the first images may have excess dark current.

The fix is quite easy. The SDK calls at the beginning of the start acquisition function should be moved to a new setupAcquisition function that is called from the writeInt32 or writeFloat64 function when any of the relevant parameters are changed.
