Ugly colorized hexdump example
#!/usr/bin/env python3
"""
A simple hex dump example with colorized output.
Per request, the output is structured with ASCII aligned
with corresponding data bytes, rather than the canonical
style typically used in hex dumps (e.g. hexdump -C).
The colorization is performed in a second pass, rather than
during a single pass, just to separate the requested example
