submodule_set_branch

Hi, thanks for creating this amazing lib! I'm looking for https://libgit2.org/docs/reference/main/submodule/git_submodule_set_branch.html I only see git_submodule_branch here: https://github.com/rust-lang/git2-rs/blob/aa0f63d6760d84cf6449ce2802394285bf3883b9/libgit2-sys/lib.rs#L2677 Is there a function to set a submodule's branch that I'm missing or is it not implemented (yet) ?
