feat: expose useActivePress

[pondorasti]

I love the concept of ejecting from the default browser active behavior and using data attributes for the new system. My only problem is that it's really hard to integrate the same UX into existing projects and frameworks.

For example, I use Next.js and I would like to have the same active attributes for the <Link> component. Exposing the useActivePress hook would allow me to create my own low level components based on the same system.
