Make eventsource.min.js really optional

[anonghuser]

The README says this about eventsource.min.js:

<!-- you can exlude this if not listening to events (may cause runtime error) -->

But the way it is bundled, it always throws an EventSourcePolyfill is not defined error even if you don't use events.

You should change the output.globals.eventsource rollup config value from EventSourcePolyfill to globalThis.EventSourcePolyfill so it just resolves to undefined when missing instead of throwing an error. Then indeed the error will only happen when you try to use events and not every time.
