RSX parser suggestion: `syn-rsx`

[stoically]

Hey, your rsx macro is probably feature complete and there's no interest in changing it – but in case you have to expand functionality: I just wanted to leave an hint for my syn-rsx crate here. I think it'd be great to combine efforts for that basic building block, and others like sauron and leptos are successfully using it.

Sorry for the shameless plug and obviously feel free to close this issue.
