Fix and refactor Channel Meta-Info (OpenEMS#1597)
The Channel Source and Target information introduced in OpenEMS#1595 was not working, because Read-Write-Channel information would always be considered a 'target' information. This Pull-Request refactors the information to a generic MetaInfo and allows explicit definition of different read- and write-registers for one Channel
