MNT: Add git-archive support for setuptools_scm

[effigies]

Types of changes

• Maintenance task: Add and test git-archive support

Summary

Versioneer permitted git archive to store some limited version information in the artifacts, such as those generated by GitHub. setuptools_scm needs special prodding to do this.

This adds and tests the feature. In the process, I've split the build and test stages from the main tests so that we can test different installation methods.

Checklist

• I have added tests to cover my changes (if necessary)

Getting bitten by pytest-dev/pytest#1596. Fortunately we're not trying to use the --dask option anywhere in CI, so just wrapping it up in a try/except.

Looks good to me. Sad for dask but looks like we are not the only one bitten by this issue.
