Add both 'muxer' and 'streams' properties to 'swarm.peers()'

[PedroMiguelSS]

Both cli commands and http api documentation say it's possible to get several details about the set of peers the node is connected to.

The returned info includes, among other properties:

• streams - information about open streams for each peer
• muxer - the type of stream muxer the peer is using

But none of this info is currently available and it needs to be implemented to get consistent with go-ipfs.

Moreover, latency is always being returned as n/a (if verbose option is set) and it needs to be properly implemented as well.

This will become possible with the new connection interface coming with the async/await refactor in libp2p. You should be able to query connections for streams and also get the multiplexer info from the stat property amongst other things.

@jacobheun I added muxer in #2681 - any way we can get a per stream protocol? https://docs.ipfs.io/reference/api/http/#api-v0-swarm-peers

[jacobheun]

@alanshaw we keep track of streams on connections now. So you should be able to use the Connection.registry Map to get the protocol and any other metadata that is saved to the stream.

js-ipfs is being deprecated in favor of Helia. You can #4336 and read the migration guide.
