Set DO flag when doing NSEC lookups.
Some DNS servers wont answer on NSEC querys unless the DO flag has been set.
Easiest patch is to add m.SetEdns0(1232, true) in DoLookupWorker but i dont know if its desired to do this on all querys.
Perhaps some flag is needed for EDNS buffer size and DO?
I think that’s probably fine to set globally for now. Can you submit PR?
