This is the annual update of the Unicode data.  I also worked a bit on 
the tooling.  The update-unicode target under meson did not update the 
data in contrib/unaccent/, so I added that.  I also fixed a Python 
deprecation warning in the generation script and made some light changes 
in the surrounding documentation.
