Title: Added handling for v3 advanced segment ids which aren't just ints as of July 15th

The old int based advanced segment ids are deprecated. The new segment ids are alphanumeric. I know from experimentation that their form includes alphanumeric and alphanumeric+hyphen. Updated code for both
cases. Reference: https://developers.google.com/analytics/devguides/reporting/core/v3/changelog
