Title: feat(datepicker): add open-on-focus option

Adds the so requested option to open the datepicker popup when the input gets focus.
I understand that it was removed to improve accessibility but in some cases opening on focus is needed.

Also, I'm not sure on how to test this, so I didn't write any unit tests :/
