[FEATURE] Allow more types of fields for additional fields.

[MattConflitti]

Is your feature request related to a problem? Please describe. It would be great to be able to have more than just text input for the sign up additional fields. Select, Numerical, SelectMultiple, Radio, Check, etc.

Describe the solution you'd like Abstract the UserFormField and create a UserFormTextField that extends the functionality. Then create the other types of fields.

Additional context This could be supplemented by just creating a new screen to route to after a successful sign up instead of adding to this package.
