This PR adds a minimal implementation of Poseidon2 from https://eprint.iacr.org/2023/323
This code is part of the work our team did during ZKHack Lisbon 2023 to implement Poseidon2 in several languages.
The circom version of the implementation is currently limited to t=3 and the bn128 curve.
A small test is also included.
