ASIdiSPIM: added indication of where scanners and piezos are that is visible from all tabs.  This was a user feature request to have easy way to make sure you are centered before making alignment adjustments.

Fix bug in MPTiff storage class. The finish() method should not return (and thus indicate that data is finished) until all pending writing tasks have completed--images and ImageJ and OME metadata. With this fix, finish() now works correctly, blocking until the writing executor terminates. Failing to do so leaves open the possibility of closing to FileChannel prior to writing completion.
