After all these years intel_bios_reader and intel_bios_dumper still manage to confuse me. Read or dump, which one decodes. Rename intel_bios_reader to intel_vbt_decode to be in line with the naming of all the other tools (particularly the closely related intel_opregion_decode tool) that decode previously gathered or dumped information.
