Adds the ability to read and write to amiibo bin files

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.
