This PR adds a suite of SHA-3 and Keccak-based constructs to the C3 standard library. This finishes rounding out the more necessary sets of C3's cryptographic hashing functionalities, and will hopefully at least equalize the power of the language in this space with the others that have these functions in their standard libraries too.
Usage
All extensive unit-tests contain each construction's usage details by example. All function calls will be well documented when this is finished.

I've included a diagram showing the high-level hierarchy used to guide me in implementing this change. The colors change the "further away" each construction is from the
Keccakbase context. Blue is no "inheritance", Green is 1 level of "inheritance", Yellow is 2, and Red is 3.This suite of functions of course uses the traditional concept of a cryptographic hash, but also incorporates the newer extendable output function (or XOF) for creating hashes with arbitrary lengths.
