The SHAKE family functions are the first formally defined XOFs (eXtensible Output Functions), previous implementations such as MGF from PKCS#1 relies on ad-hoc construction. 

In the current library, SHAKE-* are given digest-like interface, where their output has to be always obtained from the start; where as in reality, there exists applications that consumes such output progressively, such as deterministic key generation from fixed seed, and more specifically, as the random oracle used in Crystals-Dilithium post-quantum digital signature scheme. 

Therefore, I'd like developers consider adding ``shake.read(len)'' function to support IO-like consumption in hashlib.
