Better TypeScript type inference for `promiseFn` / `deferFn` args

[LennardWesterveld]

I'm missing a option like https://www.npmjs.com/package/react-async-hook has for typescript that you can give as second option a array of the values you want to give to the async function. It is also nice typed because the array says also witch value it expecting related to the async function.

Hey Lennard, thanks for the feedback. I'm looking into ways to improve TypeScript support. In fact I've already found a few places where things can be improved.

You can in fact pass additional props to the async function, but their type will just be any. I'll investigate ways to make these typed somehow, if you want you can take a stab at it. Make sure to check out #73, there's a lot of improvements in there already. 👍

how is this looking in the upcoming v10?

I suspect no change, but you can try 10.0.0-alpha.0.

It seems this is going to be adressed in #246
