Give a more specific error message when publishing a span of 0
Currently, if you try to create/edit a PI Point to have a span of 0, an error message similar to the one below appears:
Error occurred on line #, column #, while processing PI Data Archive 'PIDataArchive':
[-38] Illegal Compression Deviation Specification
Parameter name: compdev
This occurs even if compdev is not one of the published columns, which can confuse the user. Please give a more specific error message when the user tries to publish a span of 0.
