SHA512State class

The SHA512State class represents the state of a SHA-512 hash calculation.

This class is used to store the state of a SHA-512 hash, including the high and low parts of the hash state, the current buffer, the buffer's length, and the total number of bytes hashed.

Example usage:

final state = SHA512State(
  stateHi: Int32List(8),
  stateLo: Int32List(8),
  buffer:List<int>.filled(SHA512.blockSize),
  bufferLength: 0,
  bytesHashed: 0,
);

It's typically used to save the state of a hash calculation to allow for incremental hashing. This can be especially useful when hashing large data in smaller chunks or when saving the intermediate state for further updates.
