It seems like "git worktree" introduced in Git 2.5 is not supported by the library. If I try to create a Repository object with my worktree directory, or with the file path directly to the ".git" file, it says it's not a valid Git repository.

For example, I have C:\Code\Main and I use "git worktree" to create a worktree at C:\Code\Fix. I am not able to create a Repository object if I pass in either "C:\Code\Fix" or "C:\Code\Fix.git". It also doesn't work if I pull the gitdir out of the .git file (C:\Code\Main\worktrees\Fix) and pass that into the Repository constructor. (Git Extensions correctly handles the worktree so I don't believe there's any other issue at play.)

Apologies if this is covered somewhere else or if I'm just doing something wrong, Google search wasn't very helpful and the term worktree didn't bring up anything here in Issues.

I tried working around by setting IndexPath and WorkingDirectoryPath in RepositoryOptions, but it still uses the current HEAD of the original repo at C:\Code\Main instead of the one in C:\Code\Fix.
