Is there any appetite to extend lazygit to support other SCMs like mercurial?

### Is your feature request related to a problem? Please describe.

No. Requesting support/permission to extend lazygit to support alternative source control mechanisms.

### Describe the solution you'd like

Abstract out git operations to support alternative source control systems like mercurial, sapling, etc.

### Describe alternatives you've considered

Building a custom clone of lazygit. Would prefer to both contribute back to lazygit and benefit from the existing amazing community.

### Additional context

I am not asking for the community to build this -- I will. Mostly wanted to know before diving into this how open the lazygit community is to supporting abstracting out the git operations to support alternative source control mechanisms.
