threshold_crypto "community edition"

Now published as threshold_crypto_ce to crates.io for users convenience.

Originally developed by POA, with extensions from us to support 256-bit Barreto-Naehrig curve and make this library a little more pleasant.

This is a Rust crate for using pairing-friendly elliptic curves. Currently, only the BLS12-381 and BN256 curves are implemented.

Bring the threshold_crypto_ce crate into your project just as you normally would.
