wasm-bindgen-rayon and new OMT plugin (#1007)

* WIP: wasm-bindgen-rayon and new OMT plugin

* Bump package-lock

* Make OMT work again

* Update year

* Restore accidental change

* Prevent minification of `nextDefineUri`

* Delay loading external deps

This gives inline `define` calls a chance to define dependencies for earlier `define` calls on the same page.

* Add comment
