[aa2u] Make weight dynamically customizable.
* packages/ascii-art-to-unicode/ascii-art-to-unicode.el
(aa2u-uniform-weight): New defvar.
(aa2u-ucs-bd-uniform-name): Don't take arg WEIGHT;
instead, consult ‘aa2u-uniform-weight’.
(aa2u-phase-1, aa2u-replacement):
Update calls to ‘aa2u-ucs-bd-uniform-name’.
(aa2u): Mention new var in docstring.
