Estimate vibration effect size using available parcel data

While we want to avoid reading in vibration effects that are too large (which can cause the XML serialization to fail), serializing directly in the constructor to check the length causes too much heap churn. This change uses the remaining data available in the parcel to estimate the size of the vibration effect, after moving it to the end of the parcel.
