Issue description

Right now we have a finite time 'update' api. good job!

As discussed in the previous issue, this api gives users more freedom and is the basis for some speed-driven animations, hopefully soon.

tween()
    .update(
        (target: T, dt: number, ...args: R) => {
            const [speed] = args;
            target.string = String(Number(target.string) + speed);

            if (target.string === "100") {
                return false;
            }
        },
        ...args,
    )
    .start();
