dev-libs/liblouis: add 3.29.0

* Due to scripts installed with liblouis such as lou_maketable requiring
  python bindings it makes simpler to build python bindings
  unconditionally with a single python target.
* Enable python3.12 and python3.13, use PEP517 (addresses egg-info bug).
* Remove libyaml automagic.
* Install lou_maketable script dir into libexec instead of bin. This differs
  from what other distributions do as Fedora and Debian remove these scripts,
  Arch has it unchanged.
