Define canonical Geo and Network structures in annotator package

[stephen-soltesz]

This change forks the annotation-service/api types to allow:

• differentiated ServerAnnotation and ClientAnnotation types
• complete Geo2 Subdivision fields in the Geolocation type
• preserve backward compatible support for parsers using annotation-service/api types while letting the uuid-annotator archive files using canonical camel case field names.

This change also temporarily disables the asn annotator support because the type changes require a different implementation of the route view parsing and search routines. That will be added in a subsequent PR to reenable ASN annotation.
