Adds the ability to read and write to amiibo bin files (#348)

This introduces the ability to read and write game data and model
information from an Amiibo dump file (BIN format). Note that this
functionality requires the presence of a key_retail.bin file. For the
option to appear and function in the UI, ensure that the key_retail.bin
file is located in the <RyujinxData>/system folder.
