Fix Block counter starting value for PubSub
Following the release of the revision 1.04 of part 14, the OPC Foundation has issued an errata to correct the block counter starting value from:
The counter starts with 0 at the first block. The counter is incremented by 1 for each
block.
to
The counter starts with 1 at the first block. The counter is incremented by 1 for each
block.
This new definition is also present in the revision 1.05 of the specification.
This interroperability issue has not been detected sooner as there is no encrypted PubSub interroperabilty test in CI. This also needs to be changed.
