Operator proposal: retry

[sbeben]

This has been discussed in the community chat and marked as a good idea, since retrying async operations is a very common need in web applications.
I believe every second developer has done it in their own projects, so I think it would be nice to have something like:

type RetryParams<A, B, C> = {
  effect: Effect<A, B, C>
  times: number | Store<number>
  timeout: number | Store<number> | ((retryIndex: number (here we can also add params and error payload)) => number)
}

function retry<A, B, C>({
  effect,
  times,
  timeout,
}: RetryParams<A, B, C>): Effect<A, B, C>

I can provide my own implementation if the idea would be approved.

I think retry logic should me customizable, like here https://github.com/softonic/axios-retry
