Add possibility to revert the override

[teamplayer3]

I think the title describes it well. It would be cool to revert an override. This could be done by hand, by removing the line, but it would standardize the process of handling the overrides.

CLI

cargo rm-override -p <package-name>

Thanks for opening this issue. I agree this would be great to have. I'd probably go for cargo rm-override -p <pkgid> rather than a --revert flag to closer match what cargo already has for cargo add and cargo remove.

This shouldn't be too hard to implement so I'll label this issue "good first issue"

I will start working on it.
