feat: open popout with anchor coordinates (#40)

* fix: types and api of tooltip provide and popout component

* fix: auto fallback position and align

* style: move inline style to file

* feat: make popout openable with anchor cords instead of anchor element

BREAKING CHANGE: popout children forward ref and open prop is now removed with anchor prop
