I'm not sure why you need the additional parameters (`params`, `extraSalt`, `extraIterationCount`). I think you can use the existing constructor and inside `MacData`, detect if PBMAC1 is being used by checking the algorithm name, and then encode the salt and iteration count in the PBMAC1 algorithm parameters as per RFC 7292/9579.
