[issue28384] hmac cannot be used with shake algorithms

New submission from Min RK: HMAC digest methods call inner.digest() with no arguments, but new-in-3.6 shake algorithms require a length argument. possible solutions: 1. add optional length argument to HMAC.[hex]digest, and pass through to inner hash object 2. set hmac.digest_size, and use tha
