adding test cases here will lead to a circular dependency as the tests will need a ShaTweakHash from the hash-sigz lib. should be better to keep the test at https://github.com/blockblaz/hash-sigz/blob/sha-winternitz/src/tweak/tree.zig? |

added test cases and abstracted away the tweakhash to https://github.com/bhaskar1001101/tweak-hash |

hash size is not fixed to 32 and depends on the tweakable hash.
merkleizeWithTweak needs to return the entire merkle tree for the secret key. it allocates memory but might go against the design of the library? (mentioned in #17)
it is also generic over TweakHash instead of hasher as the zig-poseidon api is very different.
tests will have to be added in the hash-sigz lib as tweakable hash function is not available here directly.
