Feature: Custom commands

[Piturnah]

Type of Feature

New Feature

Description

So, gex is executing git commands under the hood most of the time anyway, so that gave me the idea
If you could use the configuration file to write keystroke sequences for custom commands where it will actually just call a custom git(?) command that you specify

Additional Information

This kind of extreme extensibility could also be a really great selling point for gex that might be somewhat unique in the world of many git TUIs. But, I'm not actually sure because I still haven't looked into what everyone else is doing enough.
