Update libp2p (#2101)

This is a little bit of a tip-of-the-iceberg PR. It houses a lot of code changes in the libp2p dependency. 

This needs a bit of thorough testing before merging. 

The primary code changes are:
- General libp2p dependency update
- Gossipsub refactor to shift compression into gossipsub providing performance improvements and improved API for handling compression
