2017-10-03Rewrite how GIF headers are readRyan Harrison
Break up reading the signature and local screen descriptors into seperate functions. Fix a bug in how matching in the signature validation works. Move LSD value assignment to after sufficient data has been confirmed. Convert LSB to MSB methods where they were just wrong. Add unit tests for ReadData, SetInputBuffer, ReadSignature, ReadLocalScreenDescriptor, and ReadHeader.
