clj-jgit.porcelain/git-add does not have a way to pass in a custom WorkingTreeIterator

I am using a custom WorkingTreeIterator with the JGit AddCommand setWorkingTreeIterator method to add custom objects into a repo.

Could this be exposed as a git-add function argument? https://github.com/Jared314/clj-jgit/commit/f6dd5da1e55bec5b624f441ba2e2b04aadf0513d
