Hacktoberfest and rust-libp2p

[umgefahren]

I authored many minor and one big pull request, that might me merged. It's not incredibly important to me, but would it be possible to add the hacktoberfest-accepted to all pull requests this month?

Is that a label we need to add? Happy to do that, please ping me on any PR that you want it on! :)

It would be a label to a PR or a Tag to the repository. I will ping you then.
