CloudTrail Global Services Logging Duplicated plugin false positive

The _CloudTrail Global Services Logging Duplicated_ plugin incorrectly reports failure when evaluating a multi-region trail. AWS recommends multi-region trails over single-region trails for most configurations, as they have several benefits over traditional single-region trails. Multi-region trails can be identified in the output returned by `DescribeTrails` by the `IsMultiRegionTrail` property being set to `true`.

The issue is a multi-region trail with global service event logging enabled will have the `IncludeGlobalServiceEvents` property set to `true` for all trails belonging to the multi-region trail. For a single multi-region trail, this should not be considered a failure result.

No file or test is named. Start at the CloudTrail Global Services Logging Duplicated plugin and inspect how DescribeTrails results use IsMultiRegionTrail and IncludeGlobalServiceEvents. Done means a single multi-region trail with global service event logging is not reported as a failure.
