The CharacterParser is responsible for taking the response from a wiki object and turning it into something usable. Most of the logic from the original GranblueWiki object ended up here.
To use, you can instantiate a CharacterParser with a Granblue ID. It will create the wiki object for you using the provided character and fetch data when you call `fetch` on the CharacterParser.
You can also fetch data for all characters with the static method `fetch_all`
Currently a specific subset of fields are persisted, but in the future more can and probably should be saved
