added retryRaise and retryEither functions

[akotynski]

Hey, with the latest API, it is easy to write Either version of the retry function. I think it could be quite useful.
I based the implementation on
public suspend fun <A> Schedule<Throwable, *>.retry(action: suspend () -> A): A

I think it might be preferable if this API used Raise directly instead. Could you perhaps make that change? It also seems like the step is only evaluated on Lefts, so perhaps in a Raise version it should be evaluated on the error type only

[akotynski]

do you mean like this?

public suspend fun <Error, Result, Output> Schedule<Error, Output>.retry(
  action: suspend Raise<Error>.() -> Result,
): Either<Error, Result>

I could even wrap it in raise context but it is not enabled in arrow

context (Raise<Error>)
public suspend fun <Error, Result, Output> Schedule<Error, Output>.retry(
  action: suspend Raise<Error>.() -> Result,
): Result

It looks great to me, but I would like to ask you to add everything to the Schedule.kt file instead. The reason is that this way the functions go into the ScheduleKt class, which makes our life a bit easier when checking binary compatibility aftewards.

Thanks for your contribution, @akotynski !

sure! Moved code to Schedule.kt file

Thank you all for your quick reply and support :)

Beautiful implementation!!
