parsing v2.0.0

This release includes significant refactoring to modernize the codebase
and improve parser generation performance by a factor of 7 to 15
depending on whether the mypycified version is used.

There are breaking changes in the exported classes:

* `Symbol`, `Token`, and `Nonterm` no longer take `parser` as the
  argument.

* The `Spec` class is no longer subclassable.  This is mostly due to its
  mypycification, but also because it's supposed to be an opaque piece
  of parser state.
