updating golang and various libs to fix security vulns

[rmb938]

Unsure if you take these types of pull requests but I've have had some security vulns pop up in scanners so just updating versions.

If this needs to be done differently just let me know and more than happy to adjust things.

Is there a chance a release could be cut including this?
