The tool and data was moved to nototools.
Makefile now needs to invoke the tool as a script, rather than passing
it to python, since the tool is no longer local. Running setup.py in
nototools will make the script accessible. Setup (apparently) copies
the script to /usr/local/bin and it is not automatically updated when
nototools changes, still need to figure out how to address this.
This script takes ~1 second for startup, so calling it repeatedly for
each flag slows the Makefile considerably, and unnecessarily since it
can be called for all the flags at once.
Now make clean takes about 1.2s, instead of 3m45s.
The bitmap emoji tools are extended to create GSUB rules for character
sequences. The images are renamed to code the character sequence in their
filenames. New images are created for ASCII digits and number sign. A new
script is added to add cmaps to the files for backward compatibility.
