Add new fields to Pii::StateId

[jmhooper]

We are planning to validate additional data that appears on the state ID with the issuing source via DLDV. In order to facilitate this new feature this change adds fields for the new attributes to the StateId struct. This struct is used to represent the State ID data when it is in the IdV session.

I'm marking this a WIP since it looks like Data does not support optional attrs. I'll need to work on this to make sure it doesn't introduce 50/50 state issues

Or switch back to RedactedStruct?

I ended up coming up with this:

def pii_from_doc
  return nil if session[:pii_from_doc].blank?
  state_id_data = Pii::StateId.members.index_with { |key| session[:pii_from_doc][key] }
  Pii::StateId.new(**state_id_data)
end

This should build out a hash with all of the required args even if they aren't present in the session.

The old implementation should be compatible since it will remove the unsupported args with Hash#slice.
