Release v0.3.1

[jp4g]

Problem

1. release 0.3.0 references noir_bignum v0.3.3 which has an issue https://github.com/noir-lang/noir-bignum/issues/25. This was resolved in noir_bignum 0.3.4 which is included here in commit 499a7f8 but is not released

2. See request for release 0.3.5 of noir_bignum- there is an additional compilation issue I won't redetail here. But in order for noir_rsa to compile with aztec-nargo, the non-ascii characters in upstream noir_bignum must be removed from the comments.

Happy Case

Would be nice to have a quick tagged release of noir_rsa 0.3.1 including described bump to noir_bignum 0.3.5 so that we can specify the dependency without local bash scripting to fix/ cloned repos

Afaik you can't patch nargo.toml if you can though pls ignore

Workaround Description

Clone downstream repositories and change dependencies, potentially pushing to forked library if critical
