Implementation of with-nasal-release

[cormacanderson]

In parallel to the prenasalised feature, we can use a postposed nasal here.

From LAPSyD:

• [ ] kŋ > kⁿ with-nasal-release voiceless velar stop consonant
• [ ] kpŋm > kpⁿ with-nasal-release voiceless velar-and-labial stop consonant
• [ ] t̠n̠ > t̠ⁿ with-nasal-release retracted voiceless alveolar stop consonant
• [ ] t̠pn̠m > t̠pⁿ with-nasal-release retracted voiceless alveolar-and-bilabial stop consonant

From PHOIBLE:

• [ ] gm > gbⁿ with-nasal-release voiced velar-and-bilabial stop consonant
• [ ] km > kpⁿ with-nasal-release voiceless velar-and-bilabial stop consonant

I would propose to deal also with prestopped nasals here, (https://en.wikipedia.org/wiki/Pre-stopped_consonant). From PHOIBLE:

• [ ] kŋ > kⁿ with-nasal-release voiceless velar stop consonant
• [ ] pm > pⁿ with-nasal-release voiceless bilabial stop consonant
• [ ] tn > tⁿ with-nasal-release voiceless alveolar stop consonant
• [ ] t̪n̪ > t̪ⁿ with-nasal-release voiceless dental stop consonant
• [ ] cn̠ > cⁿ with-nasal-release voiceless palatal stop consonant
• [ ] cɲ > cⁿ with-nasal-release voiceless palatal stop consonant
• [ ] dn > dⁿ with-nasal-release voiced alveolar stop consonant
• [ ] d̪n̪ > d̪ⁿ with-nasal-release voiced dental stop consonant
• [ ] ɖɳ > ɖⁿ with-nasal-release voiced retroflex stop consonant
• [ ] t̠n̠ > t̠ⁿ with-nasal-release retracted voiceless alveolar stop consonant
• [ ] ȶȵ > ȶⁿ with-nasal-release voiceless alveolo-palatal stop consonant

I have since realised that we actually already have this feature. Amending the issue title.

this is for those who do annotation then!
