Refactor StaticDataEndpoints to be more user friendly

[JanOuborny]

At first the endpoint should be renamed to DataDragon to match Riot's documentation naming (the old static data api was deprecated a long time ago).

Also getting data should be simplified, for example getting a champion by its id should look like this: var champion = await ddragon.Champions.GetByIdÀsync(version, id); instead of: var champion= ddragon.Champions.GetAllAsync(latestVersion).Result.Champions.Values.Single(x => x.Id == id);

Endpoints to be refactored:

• [ ] Champion
• [ ] Item
• [ ] LanguageStrings
• [ ] Map
• [ ] Mastery
• [ ] ProfileIcons
• [ ] Realm
• [ ] ReforgedRunes
• [ ] Rune
• [ ] Champion
• [ ] SummonerSpell
• [ ] TarballLinks
• [ ] Version

Hey @JanOuborny is this still up for grabs? I'd like to help out.

Thanks!
