- Use pytest4 for testing as pytest 5.x series do not work; bug

was reported upstream

- Update to 0.15.3:
  * Fix #172, catch all exceptions during extension build to reduce chance of corner cases that prevents installation.
  * Fix #171, in PVector equality comparison don's assume that other object has a length, check before calling len.
  * Fix #168, write warning about failing build of C extension directly to stderr to avoid that pip silences it.
  * Fix #155, update PMapEvolver type stub to better reflect implementation.
- Update to 0.15.2
