In the context of this library, bytes can be represented as
lists of integers between 0 and 255. Such lists can be converted to and
hexadecimal notation with the following bidirectional relation:
- Relation between a hexadecimal sequence and a list of bytes. Hex
is an atom, string, list of characters or list of codes in hexadecimal
encoding. This is the format that is used by
related predicates to represent hashes. Bytes is a list of integers
between 0 and 255 that represent the sequence as a list of bytes. At
least one of the arguments must be instantiated. When converting List to Hex,
an atom is used to represent the sequence of hexadecimal digits.
?- hex_bytes('501ACE', Bs).
Bs = [80, 26, 206].

which is often used to transfer or embed binary data in applications.
