描述
To have a higher chance to connect to peers with NODE_COMPACT_FILTERS support, we could use the service bit filtering functionality of DNS seeds.
This is not a very well documented feature, but there is some information here: https://bitcoin.stackexchange.com/questions/60373/dns-seeder-options
The filter we'd be interested in is NODE_NETWORK | NODE_COMPACT_FILTERS, so 1 << 0 | 1 << 6 = 65.
Since not all seeds support this functionality, we should fall back on a regular DNS query if we're unable to retrieve addresses from the seeds.
