@ObsidianMinor do you know why email worker wouldn't use the new interface? Will cron triggers have the same issue?

I still haven't figured it out yet - for some reason env is still not probably propagated into the rust layer, and therefore I can't seem to use bindings with it 😅

Its also quite difficult to debug because email workers can't be run locally 😅

Should we also have a new_from_stream method that takes ReadableStream?

Should we add headers field? Should these getters also be on EmailMessage?

This field should probably be optional, or maybe have forward and forward_with_headers. Or is there no difference between headers being undefined or {} in JavaScript API?

I would typically call this EmailMessageSys.

You may want to wrap these async calls as follows, otherwise the method's Future will not be Send:
let promise = self.0.reply(message.0)?;
let fut = SendFuture::new(JsFuture::from(promise));
fut.await?;Basically, you don't want to hold JsFuture across await boundary.

I may be wrong, but you may not need all of this boilerplate for types that do not need to implement EnvBinding.
Closes #274
Adds Email Worker support in workers-rs in addition to Send Email support
