Add SSE primitive and transform utilities

[davedbase]

This PR adds server-sent events to the Solid Primitives project. I developed this for a project and went a bit further with it by adding optional Worker and built-in transform utilities. The goal was to make the package composable and flexible for many uses. I rather like the idea of the transforms and might add that into the websocket package as well.

It would be nice to separate changing emails from proposing a new primitive.
Changing emails could be accepted immediately, while the primitive requires a better look.
btw to change the email on npm all packages need a patch release

Yeah, I was thinking about that as I was changing it. I reverted it back and will issue a separate PR.
