 BLAKE2 is also designed explicitly with keyed hashing in mind, making it functionally equivalent to a Message Authentication Code (MAC). The seeded constructors act as the
 keys, BLAKE2b using a maximum of the first 64 bytes of input as the key and BLAKE2s using a maximum of the first 32 bytes. Excess input is handled by passing it to the `update()` function
