## Description
For non English tracks (Swedish in my case) feat. words might be
something that ftintitle doesn't pick up.
Eg. for the song `Promoe med Afasi - Inflation`

the word `med` is `feat.` in Swedish.
With this PR you can add what ever word you wish to match as feat. so it
should cover any kind of language.
The config.yaml could look like this:
ftintitle:
custom_feat_words: ["med"]
## To Do
<!--
- If you believe one of below checkpoints is not required for the change
you
are submitting, cross it out and check the box nonetheless to let us
know.
For example: - [x] ~Changelog~
- Regarding the changelog, often it makes sense to add your entry only
once
reviewing is finished. That way you might prevent conflicts from other
PR's in
that file, as well as keep the chance high your description fits with
the
latest revision of your feature/fix.
- Regarding documentation, bugfixes often don't require additions to the
docs.
- Please remove the descriptive sentences in braces from the enumeration
below,
which helps to unclutter your PR description.
-->
- [x] Documentation. (If you've added a new command-line flag, for
example, find the appropriate page under `docs/` to describe it.)
- [x] Changelog. (Add an entry to `docs/changelog.rst` to the bottom of
one of the lists near the top of the document.)
- [x] Tests. (Very much encouraged but not strictly required.)
