Refactor azalea-client (#205)

* start organizing packet_handling more by moving packet handlers into their own functions

* finish writing all the handler functions for packets

* use macro for generating match statement for packet handler functions

* fix set_entity_data

* update config state to also use handler functions

* organize az-client file structure by moving things into plugins directory

* fix merge issues
