Base directory for worktrees

[philstainer]

First of all, wanted to thank prime for making this amazing plugin, I'm using it all the time now. Life safer 👍

So I have set up a git alias that clones a bare repo and puts all the base config inside a folder called ".bare" and the idea is that the worktrees would sit outside the ".bare" folder.

Like this:

project
└───.bare
|  .git
└─── worktree-1
└─── worktree-2

The plugin as far as I know doesn't have a way of changing the base directory for worktrees. So currently I'm having to manually specify a sub path like "../worktree-1"

I have done some playing around locally and managed to add the base_directory property as an option and I will create a pull request later.
