[feat] Add reset render props to go back to initial state

[whengely]

If I missed this in the docs, my apologies.

I have a scenario with a form where I want to be able to submit it multiple times but I can't seem to figure out how to get it back to the initial state.

I put up a quick example here just to show what I'd like.

Right now there's no way you can ever go back to the initial state, besides replacing the whole thing with a new instance of Async. We could add a reinitialize method to allow this, but you can also just make the form appear based on other state (ignoring status), such as one that you create yourself. E.g. you have a isSubmitted state value somewhere which you use to show/hide the form, and then you can reset that yourself when clicking the "submit another" button.

Nevertheless I'm open to adding a reinitialize method if you feel like opening a PR. Don't call it "reset" because that term is already used to mean clearing the form fields (which is unrelated to React Async).

Hi, I was OK without the reinitialize feature since I took the same approach as @ghengeveld mentioned. But, I tried to find the reinitialize feature at first as @whengely did. Hence I think this is good to have.

I might open a PR for this when I find some time.

Go for it 💪

After some discussion, I found the reinitialize feature was different from what I thought so I closed the PR #62.

I made a small custom hook, as a simple reference, which was I wanted.

I think this can be useful for someone in some context.

Closing the issue because this is achievable by other means as described above.
