Jujutsu support

[Elias-Ainsworth]

Is your feature request related to a problem? Please describe.
This looks like an amazing tool! But the only reason I'm refraining from using it is the lack of jujutsu support.

Describe the solution you'd like
Additional support for the jujutsu vcs that can be toggled in the config file.

Describe alternatives you've considered
The old fashioned method of amending commits.
