Reading kifuku from new pitchCategories field

[itokatsu]

Tries to handles #29
Not really happy with the code looks. We could probably rework this further to use this for all the categories.

I'm reading from PitchPosition with I've set as {pitch-accent-positions}{pitch-accent-categories} for this purpose.
We could change the pitchCategories function to use a split instead of that regex if we make a new field for categories.

Haven't tested it a lot either, but it handles おっぱい correctly.

Is there anything we can do to update the cards created before 1.4.0?

Sadly, no, unless @itokatsu knows otherwise

Oh you mean backfilling ? Sadly no way to automate this.
But you could manually write "atamadaka" in PitchCategories when you see a card wrongly set to kifuku. (or nakadaka, but it doesn't matter. The thing that matters is that it has a valid pitch type and no kifuku)
