An unsigned 16-bit integer data type for use with image networks.
Limited to only operating with the RESCALE operator for conversion
to signed int16.

Zero point can be 0 or 32768 in the RESCALE to allow for no loss of
precision (by subtracting 32768), or keeping all values as positive,
(zero point=0) with scaling/clipping as defined in the other RESCALE
arguments.

We can't easily spell check the entire specification, the
pseudocode and operator tables make it unworkable. This
adds a simple python script that tries to extract just the
description of the operators for checking. It also does a check
