Update to latest `merkletreejs` version will break a unit test in `MerkleProof.test.js`

I just wanted to let you know that if you update to the latest merkletreejs version (0.3.2), the following line will break (at least it did for me 😄):

const badProof = badMerkleTree.getHexProof(badElements[0]);

I realised it since I used the same test setup for my Vyper Snekmake foundry tests. You can fix it by adding the index of 2. See my commit here: https://github.com/pcaversaccio/snekmate/commit/0f66c3eabbd5e5a8865eab057084749ce1d6c48d:

const badProof = badMerkleTree.getHexProof(badElements[0], 2);
// or the following will produce the same result as well
const badProof = badMerkleTree.getHexProof(badElements[2], 2);

@miguelmota awesome - just upgraded and can confirm it runs smoothly. Ok, I will upgrade my Merkle proof verification tests to @openzeppelin/merkle-tree once my time permits. Closing the issue now as it’s resolved.

As frangio pointed out, the oz lib @openzeppelin/merkle-tree will supersede merkletreejs since it’ll be more well maintained in the longer term
