Wordlist optimisation based on ruleset

[mahoganyduck]

PACK rulegen works great for this, but it's got issues with very large wordlists (pythons memory usage once it hits the sorting phase).

I did rulegen against rocktastic (13G, 1.1 billion entries). That might be along the lines of what you're looking for.
