The current PR adds supports for the MiMC hash function, but on the BLS12-377 scalar's field (not to be confused with BLS12-381). The implementation is - as for its BN254 counterpart - imported from gnark's. The PR keeps support for the BN254's implementation which is used by Shomei as of now. The implementation
In more details:
Renames computeMiMC to computeMiMC254 to make the naming more specific. This can be reverted if deemed useful during the review as this introduces a breaking change.
Extends the LibGnark class to also provide computeMiMCBls12377
Adds test-cases on the Java side to check the hashes are consistent with what we get on go. The test-vectors used for the testing are the same as the one used for the Bn254 counterpart.
