Add Creative Segment Filter Support

In order to use this feature you should add at the creative level,
the "SegmentCreative" json object. Example:
    "segmentFilter": {
        "mySegmentFilter": {
            "exclude": [ "water" ],
            "include": [ "beer" ],
            "excludeIfNotPresent": true
        }
    }
Add creative segment filter for mraid capable bid requests.

This filter can be added at the creative level like this:
    "segmentFilter": {
        "supportedSDKs": {
            "exclude": [],
            "include": [ "MRAID" ],
            "excludeIfNotPresent": true
        }
    }
Also "ORMMA" and "VPAID" bid request can be filtered.
