Add reader for PicoQuant .bin files.

This adds support for one of the formats covered by https://trac.openmicroscopy.org.uk/ome/ticket/8059#
NB I am led to believe that the other format is a FIFO rather than imaging format in which case it could prove 'challenging'.
Can this be set to slightly smaller than the largest file?  That way we're sure to be testing both openBytes code paths.  128MB of pixels (so check ```32 * 1024 * 1024```) would probably be reasonable.
