Feature Request: Support Google Login

[danielfariati]

Hi.

It would be awesome if we could add google login to this tool.

Here's an article showing how to get the SAML response from Google: https://wheniwork.engineering/finally-saml-command-line-access-for-aws-sts-b0e33bbba26e

Thanks.

Here's another tool that supports federated access to AWS Role using Google SSO: https://github.com/cevoaustralia/aws-google-auth

Would love to see Google Idp added to list of providers.
