The new -limit option makes the filter operate on top N nodes by score.
This also adds ENR attribute stats in the nodeset info command.
Node set commands are now documented in README.
In Geth v1.10, we changed the structure of the "les" ENR entry. As a result, the DHT crawler that creates the DNS lists
no longer recognizes the les nodes, which is fixed in this commit.
