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
design using RHF context hooks to provide a seamless integration.
Fixes#144
Generated types for the react package were broken because they were
still using absolute imports which cannot work in standalone .d.ts
files because they cannot rely on the local baseUrl compiler option.
Thus, we introduced an alias that we are able to reliably replace
during type generation.
