lookup_rdap error without allow_permutations

[thesubtlety]

Great library, thanks! Using version 1.1.0, I'm getting an error looking up rdap data unless I used the deprecated feature "allow_permutations" (#158). No idea why but wanted to drop a note if there's a bug somewhere. Some random reddit post has the same issue saying they've seen it with government IPs and occasional corporations - https://www.reddit.com/r/networking/comments/c5d5kk/how_to_handle_asn_registry_lookup_failed/

>>> import ipwhois
>>> ip = "33.3.69.247"

>>> ipwhois.IPWhois(address=ip).lookup_rdap()

same here. I used the following workaround, without the permutations arg.

ipwhois.IPWhois(address=ip).lookup_rdap(asn_methods=['dns', 'whois', 'http'])

I removed the deprecated functionality in #230. Please try the dev branch. I am trying to expedite the next release.
