Add package level export for Public and Private Verif classes

Instead of importing from package/lib/pub_verif_token.ts (and priv
resp), users should be able to import all classes at the package level.
This commit exposes `publicVerif` and `privateVerif`, allowing users to
import all clases.
Tests and examples have been updated to not rely on the internal package
structure.
