Before moving on to GPU stuffs, we should add support for wordlist + mask
mode. However, I have doubts regarding how to proceed with this. How would
we like our hybrid mode to work?
like ?d?d?w?a?a?w where 'w' are the word from two wrodlists.
or something like -mask=?a?a -pos=N, where the mask would be inserted at
the Nth position in the word.
Though, I think the first one makes more sense as it is easier to derive
case2 from case1. We just need to split the wordlist into two using a
script.
Are we also planning to support any other hybrid modes? If yes, is it
sufficient to create an interface where we could just plug in the words
from other modes in a way discussed above. Should we focus on creating a
functions like plug_in_words_into_mask()?
