Drop redundant .has_object_permission impl on DRF 3.14.0 or above

[florimondmanca]

Closes #150

This essentially reverts #25 when DRF 3.14.0 or above is detected.

Not reverting in all cases prevents breakage (i.e. API keys not being checked anymore if using them with a bitwise OR) if people upgrade DRF-api-key while still using an older DRF.

@sparkyb Hi. I know it's been a while since you filed #150, but here's something that I think would resolve it. Would you like to review this PR so I get a fresh pair of eyes on it? Thanks!

There's something wrong with the Azure Pipelines integration -- builds aren't being triggered when I push to this branch. Need to trigger them manually… They do trigger on master though. :shrug:

I'm not as familiar with the method you're using to do the version comparison

I've just learnt myself about this. Previously I would have used pkg_resources.parse_version() but it looks like it was deprecated in favor of packaging. https://stackoverflow.com/a/21065570

Thanks a lot for the quick review @sparkyb. I think we can move forward with this change.
