Rework a bit the recent work made on RHF example to make some component
more generic, such as RhfSelect and RhfDatepicker, which is based on a

Fixes#144
Based on recent developers feedbacks that needed to use props types
in order to wrap the lib's component they were stuck because we were
not exporting all of them.
Fixes#143
