fix: make argument parsing respect quotes for high level command handler main

Api abstractions, fix gateway handler error handling, add dispatch event GuildAudtiLogCreate and update README.

Fix the example bot's package name, rename the macros subcrate to fluxer-rs-macros and set the version properly in the main Cargo.toml

Big refactor time, changes will be addressed as the next release's changelog

Added APIs, implemented more dispatch events, made an example bot implementation and a slight refactor of the repo

Implement more of the gateway dispatch events and op codes, add a better README and do a little bit of cleanup
