New description:
This ticket implements an interface to read databases of reflexive
polytopes:
* Add databases in PALP format to the `polytopes_db.spkg`.
* A class `PALPreader` that can read the palp output and yield it in
various Sage representations.
* Finally, this ticket contains a specialized PPL lattice polytope that
is fast enough to construct to go through the 500 million 4-d reflexive
polytopes and compute integral points.
