Fix write stringex (#162)

* Add StringEx.ToByteArray(...)

* Add Serialization.SerializeDataItem(DataItem)

Supports StringEx VarType or offloads to SerializeValue method.

* Use SerializeDataItem in S7WriteMultiple

* Assume string length without header in StringEx.ToByteArray

VarTypeToByteLength already assumed that StringEx declared count for
the number of characters without the header, this now matches that
behavior.

* Add unit tests for StringEx conversions

* Fix incorrect value passed to Encoding.GetBytes

The length must actually be within string limits.
