Add a try_reserve function to the mpsc Sender. This allows to attempt to query the Sender for available send slots without having to materialize the T value.

//// If the channel is full this function will return [`TrySendError`], otherwise
/// if there is a slot available it will return a [`Permit`] that will then allow you
/// to [`send`] on the channel with a guaranteed slot. This function is similar to
/// [`reserve`] execpt it does not await for the slot to become available.

If someone's going to address this typo, consider also mentioning the new try_reserve in Permit's rustdoc (currently it only mentions reserve as returning it). I can submit that PR if nobody else is on it 😄
