added reverse operation to reverse a patch

[brandonpollack23]

I needed a simple undo operation for a project I'm considering working on. I liked how simple diffy was to use so I added/tested this and thought maybe you would be so kind as to give feedback or accept it :)

Thanks for the contribution! This looks good and fairly straightforward. I'll work on fixing the lint that is failing elsewhere in the code and then I'll get this merged. And sorry for the delay!

Oh yay thank you :)

is mean here a typo? is it meant to be me or me in ?

[brandonpollack23]

Me in would be correct.
