LArRawDataReadingAlg: AutoConfigure for runs in transparent mode and be more graceful with corruption

This MR does two things:

1. Auto-configure the LArRawDataReadingAlg for runs in 'transparent mode', eg the LAr-DAQ doesn't write Energies but only raw ADC samples to byte-stream.
2. Downgrade the ERROR about unsupported ROD block type to a WARNING and change the default value of the FailOnCorruption property to false

This should address ATLASRECTS-6587 the error discussed as part of DATAP-216.
