Rename animeRenmae to match module name
Starting on CLI

Working on creating a command line interface for animeRename in Shelly.
I'm not sure if this is the optimal way to approach this, but I'm doing
it anyway because learning
Changing main is

the cli is now the main function
Maybe I should've broken the part that isn't cli out into a library, but
I guess I'll know for next time.
Had some trouble adding shelly and text, but then I just didn't
capitalize their names and it decided to start working so that was nice.
