VasprunET is now officially the default Vasprun parser.
Old Vasprun is now VasprunSAX. Note that the dielectric option is not done
because there was no unittest for it. So if things break, you only have yourself
to blame.
The new Vasprun is at least 2x faster than old one. And adding new parsing
options should now be a lot easier. Code maintenance is also easier as it is <
1/2 the length of the old unwieldly vasprun.
