refactor: -p now just sends a message with an exit code of 1 instead of a tkinter pop up
feat: added --working-dir/-w arg, that will store all the working files in feat: added a check if the user tried to use both -c and -p it would error out feat: if working directory isn't supplied it'll mke the working directly the file input fix: grammar feat: now writes json data for processed stuff, to prevent re processing if it's already been done before feat: v0.1.1
