Effectful system map debug

[Trouv]

One benefit of bevy_pipe_affect is being able to process effects before they are performed. One thing I've done a couple times is look at the effect my system is having by debugging it in an intermediate system... Something like.

my_effectful_system
    .map(|ef| {
        dbg!("{ef:?}");
        ef
    })
    .pipe(affect)

It'd be nice if this library provided a simple mappable debug function like that, so it only takes 1 line instead of 4.
