Implement a bulk write method for PIPointList

As an AF SDK developer, I would like to be able to write values in bulk to a list of PIPoints. Currently there is only PIPoint.UpdateValues() which allows multiple values for a single PIPoint object to be written in a single request. I would like to see a bulk write method against a PIPointList, similar to the bulk read methods available for that class. A key use case for this is writing data over low bandwidth and/or high latency connections.

    The ability to write directly to multiple PI Points has been available since AF Client 2012 (2.5) through the method(s) PIServer.UpdateValues. See https://techsupport.osisoft.com/Documentation/PI-AF-SDK/html/Overload_OSIsoft_AF_PI_PIServer_UpdateValues.htm

    There you go. For some reason I never thought to look under the PIServer class methods for this.

    We will add a link from PIPoint.UpdateValues documentation so it is more obvious in the future as the pattern is slightly different than other operations.
