re_nfpii: reimplementing the Wii U amiibo library

re_nfpii reimplements the Wii U nn_nfp.rpl library for amiibo emulation and research. Its module replaces the library's exports and redirects tag reads and writes to SD-card dumps, while a companion plugin provides selection and configuration. The author describes the work as experimental and says it currently covers the major parts of the library.
