* adding stuff for writing a supercluster with updates information, using correct rotation * fixed a few more bugs in this class forgot about * move the "fakesign checker" stuff to a more appropriate place * add a couple small functions to TMD, ticket, shardeMap * add a new "demo" program/project nandBinCheck. it does lots of useful integrety checks on a nand.bin that will be needed when starting to actually write these things
