add tox and switch to GithubAction

[vincentsarago]

👋 This pr does:

• switch to GH actions 🤷‍♂️
• add TOX for testing multiple python versions 🤷‍♂️

To be discussed

• pre-commit integration?
• pypi publish from CI?
• mkdoc / gh-page?

[vincentsarago]

I guess you need AWS credential to be able to use S3 file 🤷‍♂️

[geospatial-jeff]

Yeah should really use moto so we don't need to talk to S3 at all for tests

[vincentsarago]

TDB

[vincentsarago]

we can remove this if S3 credential is not needed

[vincentsarago]

when trying to run the test within tox I get

[vincentsarago]

aioboto3, depends on aiobotocore which depends on specific boto3 and botocore versions. It's easier to let hem decide the version they need ;-)

[vincentsarago]

I think this is not needed in fact!

[geospatial-jeff]

I pulled down your changes, ran tox and it worked 🎉

[kylebarron]

You might be able to merge this onto a non-master branch, and then CI might run?
