Support ALBs and NLBs in addition to ELBs about cloudmapper

ALB and NLB support should work now thanks to @JulesDT and @heikkiv.

I can probably do that. Do we agree that (in terms of AWS CLI)
aws elb describe-load-balancers gives you the ELBs
aws elbv2 describe-load-balancers gives you the ALBs and NLBs ?

Obviously AWS didn't make this easy so the JSON Blobs structure is different, but no big deal.
Could someone eventually give some demo data so that I can test my code ?

Opened a PR (#61) to solve this issue, but I couldn't test it.

Thank you @JulesDT! I'd like someone else to test this with real data, and if possible update the demo data with some munged data so the unit tests run over this. I can spin up an ALB and NLB quickly if no one else already has one in their environment.
