* Move app/helpers/granblue_wiki to lib/parsers/wiki
This clears up the namespace beginning with "Granblue"
* Removed some top-level Granblue libs
DataImporter and DownloadManager exist inside of the PostDeployment namespace now so these files are redundant
* Fix Downloaders namespace
Our namespace was singular Downloader, now it is plural Downloaders to match the folder name
* Fix import paths
* DownloadManager was moved to downloaders/
* import_data task now uses the PostDeployment version of DataImporter
* Update application.rb
Eager-Load/Autoload the lib/ folder
* Update cors.rb
Add Granblue website and Extension ID to CORS
* Add transformers
Transformers take raw data from Granblue Fantasy and transforms them into hensei-compatible JSON. Transformers heavily borrow from vazkii/hensei-transfer.
* Add ImportController and route
This adds the controller that handles creating a full party from transformed Granblue Fantasy data
