feat: implemented BLAKE2b cryptographic hashing algorithm (#1230)

* feat: added BLAKE2b with one working assert
docs: added BLAKE2b to README.md

* [enhancement] added more doc comments and fully implemented BLAKE2b key hashing

* fix: forgot to add arg

* chore: applied clang-format

* updating DIRECTORY.md

* docs: added main function docs

* docs: added documentation for #include's

As requested by Panquesito27 in #1230 (comment)

* docs: added algorithm description

As requested in #1230 (comment)

* docs: added reasoning for warning suppression pragmas

* docs: spellcheck and additions

Added doc for bb definition.
Added description for mixing function G and compression function F.

* Added print statement to let user know tests have passed

* Updated doc comments for variables

* docs: removed old doc comments

* fix: had minus sign instead of assignment operator

* chore: replaced uint64_t[16] with block_t type to improve readability

* docs: defined macro constants to reduce magic numbers

* fix: fixed memory leak in blake2b()

* docs: moved comment

Moved comment about the suppressed warning directly above the code that emits the warning

* docs: added psuedocode/feat: added u128

Added psuedocode for the algorithm in doc comment for BLAKE2B(). Added return docs for void functions. Defined an unsigned 128-bit integer to match the max input size specified for the algorithm.

* fix: fixed build errors

* docs: added some clarifying comments

* docs: reduced magic numbers
