feature: Add clockForKleisli and sleepForKleisli

[geny200]

Hi, I suggest to add same functionality from cats for effects, so I opened a small pull request to demonstrate what I propose. If it's ok, then in the new PR I'll do it for all transformers and all effects.

Here is an example with a demonstration of the problem: In the first case, with cats everything is fine; in the second case, the ide says that everything is fine, but we get a compilation error.

  import cats.effect.{Clock => CatsClock}

  // Ok
  def catsClock[F[_]: Monad: CatsClock]: F[FiniteDuration] = {
    val clock = CatsClock[ReaderT[F, String, *]]
    clock.realTime.run("str")
  }

  import tofu.time.{Clock => TofuClock}
  
  // Error `could not find implicit value for parameter e: tofu.time.Clock[[╬│$1$]cats.data.Kleisli[F,String,╬│$1$]]`
  def tofuClock[F[_]: Monad: TofuClock]: F[Long] = {
    val clock = TofuClock[ReaderT[F, String, *]]
    clock.realTime(SECONDS).run("str")
  }

Thx for contribution!

Yeah. I think it's a good idea to provide instances for transfomers as CE does.
