As others have said, PIL has the 'histogram' method to do most of the
work. However, as histogram works on each band separately, you have
a bit of preliminary programming first to combine them.
The ImageChops darker method is one easy-to-understand way (done twice),

You want your file considered as a sequence of bits rather
than a sequence of 8-bit bytes, do you? is the 10-bit
bit-pattern to be stored at an arbitrary bit-position in
the file, or is the whole file regularly subdivided
at 10-bit intervals?
