This PR fixes a mistake in Inventory ID 1284 (Mada):

https://phoible.org/inventories/view/1284

and changes eʲ to e (as per the grammar) in the raw data file:

https://github.com/phoible/dev/blob/master/raw-data/PH/gm-afr-inventories.tsv#L1977-L1978

This PR also fixes segments in Inventory ID 1927 (Mỹky):

https://phoible.org/inventories/view/1927

originally from SAPHON source, raw data file:

https://github.com/phoible/dev/blob/master/raw-data/SAPHON/saphon20121031.tsv#L129

and removes the segments (õʲ, aʲ, oʲ) as they do not appear in the original source:

@drammock -- had to merge in your previous PR (#358) and regen the phoible csv file.

[drammock]

ok. Just a heads up to (usually) not do that with open PRs. In this case (merged PR) it should be fine, though in this case it's equivalent to merging in main (which is pretty much always OK/good to do if your PR branch is behind main).

Is this ready for merge then?

[bambooforest]

Thanks for the heads up. Yes, it's ready to go.
