Support for IProgress

Hi,

would it be possible to add animation progress support via IProgress interface? Progress would be normalized value (0..1), used like so:

await anime.Play([animation], Progress.Create<float>(x => { if (x > .05f) Debug.Log("After 50%);}))

using ValueTuple instead Tuple may be better with GC.

New syntax

Before

await Anime.Play(
    Easing.Create<InOutQuad>(beforePosition, toPosition, 0.5f),
    TranslateTo.GlobalPosition(target)
);

↓

After

await Easing.Create<InOutQuad>(beforePosition, toPosition, 0.5f).ToGlobalPosition(target);

A to B to A on Single Animator

Anime.Play(
    new Vector3EasingAnimatorMid(
        new InOutCirc(),
        new Vector3(0f, 0f, 0f),
        new Vector3(2.5f, 2.5f, 2.5f),
        new Vector3(0f, 0f, 0f),
    duration),
    TranslateTo.LocalScale(discObject)
)

public class Vector3EasingAnimatorMid : IAnimator<Vector3>
{
    private readonly IEasing easing;
    private readonly Vector3 start;
    private readonly Vector3 mid;
    private readonly Vector3 end;
    private readonly float duration;

    public Vector3EasingAnimatorMid(IEasing easing, Vector3 start, Vector3 mid, Vector3 end, float duration)
    {
        this.easing = easing;
        this.start = start;
        this.mid = mid;
        this.end = end;
        this.duration = duration;
    }

    public void Start()
    {
    }

    public Tuple<Vector3, bool> Update(float time)
    {
        var t = Mathf.Min(time / duration, 1f);
        if (t < 0.5f)
        {
            t = t * 2f;
            return Tuple.Create(Vector3.LerpUnclamped(start, mid, easing.Function(t)), time > (double) duration);
        }
        else
        {
            t = (t - 0.5f) * 2f;
            return Tuple.Create(Vector3.LerpUnclamped(mid, end, easing.Function(t)), time > (double) duration);
        }
    }
}
