Add support for an undocumented (at least in free60 wiki) optional header for installer packages in STFS

Example InfoPrint output:

Installer Information
  -------------------------
    Installer Type: 53 55 50 44
    Installer Type (Parsed): SUPD
    Installer Base Version: 0 (0x00000000)
    Installer Base Version (Parsed): 0.0.0.0
    Installer Version: 540098816 (0x20314100)
    Installer Version (Parsed): 2.0.12609.0

Also, STFS is all big endian except the volume descriptors
Because nothing is ever nice
