Proposal: Use async iterator instead of observable

[cmdcolin]

would potentially simplify the API, or at least, some people find the RxJs terminology sort of foreign and this would be native js concepts. note that async iteration is sort of a bleeding edge thing and it also needs to be done carefully.

I tried doing this a little naively but just made a mess of trying to thread generator functions all the way through the code. I think probably that might not be necessary for every function to be a generator, it just needs to generate the promises necessary and stream them in at one location
