Update: Add 3 presentation modes to byte_dump: normal, simple, and classic

Normal presentation will replace ASCII control or whitespace character with the UTF-8 characters that represent this with a picture character.
Simple presentation will use a single space to represent any given ASCII control or whitespace character.
Classic presentation will do what the "hexdump" tool traditionally does and use a single period to represent an ASCII control or whitespace character.
