A hex digit is 4 bits long. To separate into words, the 24-bit word
Python would use 3 (counting in bytes as initially proposed), or 6
(counting in hex digits). Neither option would result in a 1.5
chunk_size for 24-bit chunks.

Counting chunk_size either in nibbles or bytes seem equally intuitive to
me (as long as it's documented).
