Finite Field Infrastructure

Overview

This crate provides the necessary infrastructure to work with finite fields for cryptographic applications, including prime fields.

The crate is freely inspired by ff with only a few minor improvements, and it's published as starkom-ff.

For reference and testing purposes, this crate also provides an implementation of the BLS12-381 scalar field (order 0x73eda753299d7d483339d80809a1d80553bda402fffe5bfeffffffff00000001) based on our own Field256 and PrimeField256 traits.
