[Feature Request] Reversing Hunks

[KodyVB]

Is your feature request related to a problem? Please describe.
If I'm looking through recent commits and find a hunk I want to reverse, I don't think there's currently a way to easily do so outside of taking note of the filename and line number and manually changing it.

Describe the solution you'd like
Like staging/unstaging sections by just hovering over the hunk and pressing s or u, it would be nice to be able to reverse a hunk to a previous commit's state by hovering over that hunk and pressing some key combination.

Describe alternatives you've considered
Manually changing the lines in question is what I usually wind up doing, but the following command does similar to what I was thinking:

git checkout -p [highlighted commit]^1 -- path/to/file

With the caveat that the above command will interactively walk through all of the hunks rather than being able to just select the one.

Additional context
I don't use emacs, so I couldn't confirm if this is exactly what I was thinking of, but it does seem like magit has this feature here.

I had a go at implementing this in #1599, feel free to checkout it.
