Create start of perl6 version of script. Rakudo is dog slow on it (~7 seconds to read file, ~10 minutes to create the Trie, for comparison perl5 is instantaneous). I'll see if niezca fares any better.
Make compatible with niecza for 5x speed increase for initial trie creation.
Make perl6 version slightly faster to generate by removing the whole trie thing (though the name remains, I should fix that).
