BytesToUint64Array converts a slice of bytes to a slice of uint64 integers.

calculateHash computes the SHA-256 hash of the input byte slice.

The `ConstantTimeCompare` function is used here to securely compare two hash values.

GetlogLevel gets 'slog' level based on severity specified by user.

NewLogger returns new slog ref.

PackUI64 takes a data type (in the form of a byte), a pointer (offset in memory), and a size (amount of memory/data to consider).

uint64ArrayToBytes converts a slice of uint64 integers to a slice of bytes.

UnpackUI64 reverses the operation done by PackUI64.
