fixes #872

distutils.version.StrictVersion cannot parse numpy development versions like 1.19.0.dev0+578f4e7. LooseVersion is able to parse the version, but it compares

>>> LooseVersion("1.19.0.dev0+578f4e7") < LooseVersion("1.19")
False

Using pkg_resources.extern.packaging.version.parse instead makes this work as expected. Since setup.py requires setuptools, I think it being installed is a reasonable assumption?

See also #872, maybe we can fix both things at the same time.

it's now in install_requires. Is that the right place to put it?

926: use packaging.version.parse instead of StrictVersion for version checking r=hgrecco a=keewis

fixes #872

`distutils.version.StrictVersion` cannot parse numpy development versions like `1.19.0.dev0+578f4e7`. `LooseVersion` is able to parse the version, but it compares
```python
>>> LooseVersion("1.19.0.dev0+578f4e7") < LooseVersion("1.19")
False
```
Using `pkg_resources.extern.packaging.version.parse` instead makes this work as expected. Since `setup.py` requires `setuptools`, I think it being installed is a reasonable assumption?
