Separate NIFFileReader from NIFFile

NIFFile might not always be created from a file or stream containing NIF data.
Basically there are 2 different responsibilities for this class:
1. Read NIF file
2. Provide input for nifosg and bulletnifloader.

Remove no longer needed NIFFileMock since the state of NIFFfile can be
initialized independently from reading NIF file.
