Release v2.2.0

A large update, inspired in part thanks to the Cookbook Jam

Changes:

• Slight restructuring of the library, however code for version 2.1.0 is mostly compatible with this new version
• error callback now only takes 2 arguments instead of 3, status and options
• Hooks for HTTP Parsers have been added, a JSON parser is included and enabled by default
  • More information here: https://docs.sidorakh.net/http.gml/#/2.2.x/http-body-parser
• The options struct has new options
  • More information here: https://docs.sidorakh.net/http.gml/#/2.2.x/http?id=structhttpoptions
• Limited JSDoc is applied to each function in the library (I can't be sure it's all accurate, if there are any problems with this, please open an issue)
• Feather comments are placed throughout the code so no new warnings should pop up, outside of naming rules
