elliptic-curve v0.14.0 release tracking issue

[tarcieri]

This is a tracking issue for remaining work items and blockers that remain for an elliptic-curve v0.14.0 release

[tarcieri]

The main blockers here are upstream releases of ff/group.

I made a ticket of items I would like to see included in the group v0.14 release: zkcrypto/group#80
