Override writedata / writeflags / writeweights in output
Created by: tammojan
It could be useful to disable updating the data column (or flag, or weights). A use case for this would be to apply a rough bandpass before flagging. After that the flags would need to be stored, but not the data with this bandpass (which could be calibrated later).
Could be trivially implemented by adding a parsetkey msout.writedata
which would override itsWriteData
in MSUpdater.cc (similarly for weights, flags).
