Increasing output pad values reduces the size of the output
region in the old definition. This is counter-intuitive.
This patch inverts the sign of the output pad values such
that increasing values leads to increasing pad. It also
specifies a pad limit range of output pad values that
give an output dependent on the whole input.

This converts portions of the asciidoc specification into an xml
document and schema. For the html and pdf outputs, the xml is
converted to asciidoc files that are included into the existing
specification.
The xml allows future automated uses of the tosa specification
while maintaining rough compatibility with the existing document.
No significant functional changes are included in this change.

The current value is too strict, and can lead to some cases to fail.
By making the new value limit between (-1 << shift-1) and (1 << shift-1),
we still restrict the input value a range that works for optimized implementations
that left shift their values before multiplying.

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
over the entire license.
A custom dictionary is used to contain specification custom words.
