Count same letter again with given flag

[Deadairx]

as a user, I would like to have my cypher key count reoccurring characters in the pangram again and use them in the cypher.

This should happen when given --count-multi in the arguments.

The encrypted text should also make use of the reoccurring characters and cycle through them in order. (if o = 7, 28 then ooo should output 7.28.7)

if used with --slide [number], the count will not circle back to 1 after 26, but instead will continue counting up
