Implement checking of FrameReceiver status before starting acquisitions

[GDYendell]

Previously the FrameProcessorAdapter performed checks via the FrameReceiverAdapter that the frameReceiver has all of its free buffers available to avoid confusing failures. This was removed here.

The generated start_writing method should be disabled (.enabled = False, e.g. here and a @command method added to FrameProcessorController the does the checks and then calls the start_writing method, which is still available internally, just not exposed to the transport layer (I think).

Acceptance Criteria

• FrameProcessorAdapterController does not allow start writing if frame receiver status is bad.
