Creates a SHA1 hash function.

FNV24: [8I8VR]

Initialize a new hash function by calling this method if you want to hash the data iteratively, such as when you don’t have a buffer large enough to hold all the data at once. Provide data blocks to the hash function using the update(data:) or update(bufferPointer:) method. After providing all the data, call finalize to get the digest.

If your data fits into a single buffer, you can use the hash(data:) method instead, to compute the digest in a single call.
