PEL: MTMS class to handle the type-model and SN
This class represents the (M)achine (T)ype-(M)odel (S)erial number
structure for the PEL, where it is used in both the ExtendedUserHeader
and FailingMTMS sections.
It consists of an 8 byte machine type+model field of the form TTT-MMMM,
followed by a 12 byte machine serial number field. Unused bytes are set
to 0.
Note that this is not a PEL section itself. It's just used by other PEL
sections.
