I haven't changed the javadoc to match the implementation, as it seems that a first review is likely to have an opinion as to API changes |

Description of changes:
Minimal change to avoid calls to Mac.getInstance
Call to this were only used to extract the provider, which I though would be better expressed as an enum, as there are very few MacAlgorithms in use.
In my (closed source) benchmark this call accounts for 5.6% of the CPU time taken for a decryption (a call to
AwsCrypto.decryptData), with small payloads, and thee same for encryptionI cant fully build this locally so cant run a test cycle prior to submitting this PR
