py-parso: updated to 0.7.0

0.7.0:
- Fix a lot of annoying bugs in the diff parser. The fuzzer did not find
  issues anymore even after running it for more than 24 hours (500k tests).
- Small grammar change: suites can now contain newlines even after a newline.
  This should really not matter if you don't use error recovery. It allows for
  nicer error recovery.
