ipset revision usage is inconsistent with ipset binary from netfilter

[bleggett]

Example:

For hash:ip,port, this library defaults to revision=1: https://github.com/vishvananda/netlink/blob/main/ipset_linux.go#L398.

But the ipset binary code comments indicate we should be using at least revision=3 here (since this library supports using comments with that set type) https://github.com/Olipro/ipset/blob/9f145b49100104d6570fe5c31a5236816ebb4f8f/kernel/net/netfilter/ipset/ip_set_hash_ipport.c#L30

For hash:ip, this library defaults to revision=0. But the ipset binary code comments indicate we should be using at least revision=2 here (since this library supports using comments with this set type as well): https://github.com/Olipro/ipset/blob/9f145b49100104d6570fe5c31a5236816ebb4f8f/kernel/net/netfilter/ipset/ip_set_hash_ip.c#L28

In general, we should probably track the set-level revisions that the ipset binary does.
