Update Go versions used in CI

• Remove < 1.13 and possibly < 1.16
• Add 1.18

The current CircleCi config fails when Go 1.18 is added.

See related

• Check for and report bad protocol in TLSClientConfig.NextProtos #788 (requires Go >= 1.13)
• Replaced the deprecated ioutil package #776 (requires Go >= 1.16)
• test for github actions and remove old golang version #778 (edits CircleCI config, adds GitHub action)

I do not have time to work on this. It will be great if somebody else can investigate.

Oh oops, I just got the PR ready for a review where I added 1.18 for Circle CI - can prepare another that moves the CI off Circle CI if that's preferred.

Initially, I was in favor of moving from Circle CI to Github Actions. I went through a couple of blogs and links. I think we are doing okay with Circle CI.

Here are the links to articles I went through:

3. https://circleci.com/circleci-versus-github-actions/
4. https://www.tinystacks.com/blog-post/circleci-vs-github-actions-which-is-better/

I will review PR in some time.

Thank you
