go: update to version 1.18

[KarthikNayak]

Go only supports -2 major versions. Currently we're on Go 1.20, so the last supported version is 1.18.

Let's update the library from Go 1.17 to Go 1.18

@bzz could you have a look at this? Also seems like a release is due, maybe after this?

I can merge it, because I do not see any risk in the PR, but I think the right person to tag a new release is @bzz
