Subject: [PATCH] Build a new NACP if the NRO does not have one

It creates a fairly basic NACP but all values should be sane for a simple NSP Forwarder. The only thing that could reasonably be improved is the Titles and Ratings, e.g., different tiles and ratings for each language and region.

This introduces 3x dependencies, bs4, lxml, and hptnacp.
