Carriage returns in labels

[dinamic]

Heya 👋

I'm trying to bring up to speed an old project and it has a dependency on an old fork of this repository.

It's been a while since it's been forked and I was wondering if carriege returns are supported in labels. If not, are there plans to add support for them?

Here's the full diff the fork of the library has:

main...Trismegiste:graphviz:master

I've address newlines not being escaped in 65fa935 and released v2.0.1 containing it.
