Refactor and enhance handling of payloads and data structures
Added support for handling various payload types, including GPS and alarms, with new structures and constants. Introduced helper methods for JSON marshalling/unmarshalling of GPS data and modularized the handling of certificates, configurations, and alarms. Implemented foundational server code for testing and expanded several package functionalities.
