PEL: Create object for every section
When unflattening a PEL, create objects for every PEL section in the
log. It will use a factory method to choose which object type to create
based on the section ID in the section header. All of these object will
go into a vector of Section objects, which is the base class for every
PEL section class.
The factory will default to creating a Generic object when it doesn't
have any other type to create.
