Error parsing multiple ASNs from reverse lookup

[rshipp]

Ran into this issue using GOSINT, originally opened an issue there (ciscocsirt/GOSINT#19), but moving it here as it seems to be a bug in this library.

When the lookup returns multiple ASNs for a given IP, it tries and fails to parse as a number:

2018/02/22 09:43:48 Error doing reverse lookup on %v: %v 103.235.224.237 Could not parse ASN (4808 23724 56282): %!s(MISSING): strconv.Atoi: parsing "4808 23724 56282": invalid syntax

2018/02/22 09:43:59 Error doing reverse lookup on %v: %v 106.75.101.69 Could not parse ASN (4808 23724): %!s(MISSING): strconv.Atoi: parsing "4808 23724": invalid syntax

(Note the above output is from GOSINT.)

These IPs are from the CI Army blacklist, http://cinsscore.com/list/ci-badguys.txt, there's about 160 IPs out of the 15k on the list that trigger the error.

fixed via d231a84

It will now ignore subsequent ASNs.
