PEL: Add UserHeader class
The second section in a PEL is always the 'User Header' section. This
commit adds a class to represent that. Right now, the only constructor
available is filling in its data fields from a PEL stream.
Several of the fields in this section have predefined values that are
defined by the PEL specification. Defining any constants or enums for
those will be left to future commits where they will actually be used.
