		## RxJS `fromEvent` types inference

		The default `fromEvent` from RxJS will return an `Observable<unknown>` for our typed emitter.

		This can be fixed by the following code, by replacing the `fromEvent` type with our enhanced one: `FromEvent`:

		```ts
		import { fromEvent as rxFromEvent } from "rxjs"
		import { FromEvent } from "typed-emitter/rxjs"

		// The `Observable` typing can be correctly inferenced
		const fromEvent = rxFromEvent as FromEvent
