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'.
I'm a little concerned about the memory usage here.  For now, it's probably fine, as the largest file we have is 197MB, but going forward it may be worth trying to limit the number of timebins that are cached (e.g. read at most 128 at a time).
