Refactoring for NCAContent, NCAController.

Browse source 
Add export function to NCA content to get is as it (has to be used to export RomFS blob) + add exporter class to export it in similar to ISuperProvider.class / Extractor.class manner with keeping names agreement.
Add custom exception to notify emptiness of the NCA section since using NullPointerException could discourage.
