Would you accept a PR that made the pcap-parser turned into async Rust?

Hi,
I am not sure moving to async-only would be a good move. At the moment, one possible thing would be to make the crate async-compatible (maybe using a feature?), but I'd like not to force all dependencies to become async.

This is only a first feedback, and I'm open to debate. If there are strong arguments I do not know, please add them to this discussion. I'd also be interested in discussing if you have some experience with async, because my first experiments for pcaps were quite dissatisfying, yet I think I am to blame for the lack of knowledge and the poor choices of design for my async tests.
