Nasal release vs. pre-stopped nasals

[drammock]

S. Moisik points out that our feature set probably can't distinguish between a pre-stopped nasal and a stop with nasal release. This is possibly even a within-language contrast in Wolof? Will need to think about how to distinguish these segment types featurally.

Note that we also talked about adding general phoible features for IPA.

This might be helpful in that regard:

I'll investigate.
