Check for consistency in COVID-19 DV variables, DVREAS and DVEPRELI

This check looks for inconsistency between DVREAS and DVEPRELI. If DVREAS indicates a COVID-19 related deviation, then DVEPRELI should not be missing and vice versa. This check applies to studies using the Protocol Deviation Management System (PDMS).
