PEL: Add a flatten() to Section base class

To prepare for supporting PEL sections that can be in any order,
which will probably be stored in a std::vector<unique_ptr<Section>>,
add a pure virtual function in the Section base class so this list
of sections can just be iterated on and have every object in it
flattened.

This flatten() call replaces the operator<<(Stream&, <object>)
functions currently in use, so also convert the operator>> to
unflatten() to make things consistent.
