Went out on a limb and merged this, even though I'm not a python dev.

let me know if it causes any issues and I'll help resolve.

Did the travis CI actually run after merging this PR? I believe a release will need to be made for this to actually have any affect. EG push the wheels to pypi

Since June 15th, 2021, the building on travis-ci.org is ceased. Please use travis-ci.com from now on.

Don't know if travis-ci.com is the same as travis-ci.org, maybe we need to switch to something else.

[michael-grunder]

Travis deprecated all of their .org repos and asked that people migrate to .com. I ended up just migrating hiredis and phpredis to GitHub Actions, so that's an option.

We could also just migrate to .com but I think that would require someone who is an admin for the redis org.

[ifduyue]

There is PR #120 for migrating to github actions.

When will this be in a release?
