cbfstool: add unprocessed flag for file exporting
Add an unprocessed flag (-U) which modifies how files are exported. In the case of a compressed raw file, extract without decompressing. In the case of a stage or payload, extract without decompressing or converting to an ELF. This can be useful for verifying the integrity of a stage or payload, since converting to an ELF may not be a deterministic process on different platforms or coreboot versions.
