Description
PicamAdvanced_RegisterForAcquisitionStateUpdated()
registers a function to
call during data acquisition when the camera transitions to an acquisition state.

the functions are called in the order in which they have
been registered.
Callbacks are called asynchronously from another thread, but are serialized on that

after each callback returns.
