Added Support for 532-Byte Amiibo BIN Files (#412)

Browse source 
Added functionality to load 532-byte Amiibo BIN files, commonly used in
Tagmo and similar tools. These files were missing the following pages.
*    133 (85h) PWD
*    134 (86h) PACK RFUI
These pages can be added as null bytes if not present. The system seems
to function correctly without them.
