Cannot use field type twice

Trying to import two phone numbers, one into phone_number and one into mobile, fails, because the field type is used as column name when calling Pandas.

Exception:

Template snippet:

    - field_type: phone_number                                                                                                                         
      db_field: mobile                                                                                                                                 
    - phone_number

The db_field should be overridable for all field types. Probably, args should simply be loaded verbatim and set on the class (using setattr) verbatim.
