Version 5.3 Build 4
This is a minor update that fixes an edge case where an incoming log message does not contain a severity flag.
- Added a null check to the GetSeverityAndFacility() function that returns a ("No Facility", "No Severity") tuple.
- The GetSeverityAndFacility() function now returns a proper tuple value if it can't parse the Integer, namely ("No Facility", "No Severity").
