PEL: Add a Generic section object

This object will be created when unflattening a PEL when there is no
other class to use for that section.  It just contains a vector<uint8_t>
for its data.

This is done so that the code can always have objects for all PEL
sections, which helps in validating (can at least ensure every section
has a valid header and size), printing (will always have an object to
get its data to at least hex dump), and re-flattening (no need to keep
around the original data buffer).
