feat(checkbox): add checkbox to pickup ui

[wliederer]

Made checkbox for pickup ui

created two tests:

1. to check to checkbox renders without crashing and matches snapshot
2. to check that prop checked=boolean can be passed and the box can be clicked and change its checked state.

Looks good and works internally. However, right now, there's no way for the parent to see the state of the checkbox. I'm thinking it may need a handleChange or onChange prop to receive a function from the parent, maybe lifting state as well if needed.

I added a required onChange function pass that works with internal checkbox state to work with parent state. I looked at the prop-picker when thinking of an implementation for it. Open to other ideas wasnt really sure how to approach this one. I put invisioned implementation in playground.

Let me know what yall think
