On non-FHS systems like NixOS, there is no `/usr`. Additionally, Nix has
immutable packages so mbrola cannot be installed to espeak-ng’s
`datadir`. Instead, packages are expected to find data under one of the
paths listed in `XDG_DATA_DIRS` environment variable, as defined in the
[XDG Base Directory
Specification](https://specifications.freedesktop.org/basedir-spec/basedir-spec-0.6.html#variables).

number_buf, breaking the CI on ubuntu amd64 clang+msan, ubuntu

While this probably deserves cleaning up, we'd rather not break the CI,
to be able to properly track regressions.

Data for the constructed art language Xextan, adapted for current

I added initial support for Faroese language. Did the rules for most
common phonetic rules that are in place for Faroese, and the ability to
more easily make improvements to the phonemes, rules, and exceptions.
Current status is early testing, but voice is mostly understandable at
this point, and pronounces numbers by the correct rules now.
