Create github actions

[kmacdonald-stsci]

Created github actions workflow to perform pytests on two python versions, as well as testing a document build.

[pllim]

Please squash out blank.yml and delete .travis.yml.

Why not use RTD PR builder?

[kmacdonald-stsci]

I removed .travis.yml. I renamed the github action blank.yml to spherical_geometry.yml.

[pllim]

Also add a badge to README.

AFAIT there's a consistent issue with the RTD doc builder. I suspect it needs higher permissions to sync the webhook than any of us has. I'll contact someone else about this but meanwhile I think this is OK to go without it.

[pllim]

Huh! I didn't have that problem with my own spacetelescope repos. I wonder what changed since I set it up.

@mcara I see that the above check for continuous-integration/travis-ci seems to be required for PRs to be merged. Now that Travis CI is being removed, this should be changed in the settings.

Looks good!

At some point in the future if we switch to using tox here, it might be good to run tests on the installed version of the code, especially since this has a bunch of C code. But that's for a future task I think.

[pllim]

I dunno about tox. I am struggling to get it to find my C-ext over at synphot. No one could figure out why... spacetelescope/synphot_refactor#295

I kinda regret switching to it.

@mcara I see that the above check for continuous-integration/travis-ci seems to be required for PRs to be merged. Now that Travis CI is being removed, this should be changed in the settings.

How should I do this? I removed travis from webhooks but it did not have any effect. @pllim can you advise?

Maybe simply merging this PR will remove travis requirement?

continuous-integration/travis-ci

It is under Settings -> Branches (branch protection rules). I updated it to require subset of Actions CI and not Travis CI anymore.

[jdavies-st]

Looks great! I think this is ready for merging @mcara .
