Add compatibility with Go 1.23

[yorickdowne]

Projects that include memsize tend to fail with link: github.com/fjl/memsize: invalid reference to runtime.stopTheWorld

Compilation with Go 1.22 works

[fjl]

I tried... golang/go#68167

[fjl]

Projects which are forks of go-ethereum can apply this patch to remove memsize: ethereum/go-ethereum@e467577

Thank you!

I will leave this open for now. Perhaps a solution can be found.

I'm considering to publish a new version that just panics on Go 1.23. That would be for downstream consumers who depend on memsize via another project, but are affected by the issue.

Would appreciate it. I had to build something that uses your library as a transient dependency for a demo, and I did the naive thing of installing the latest version of the Go compiler. A message telling me that you're only compatible with < 1.23 (and perhaps linking this issue) would have saved me some panicked searching.

I don't really know where to put the message though. In the repo description?

What you've got in #6 seems fine, just add "for more information, see github.com/fjl/ memsize/ issues/ 5" (spaces where added due to GitHub's auto formatting)
