Discuss naming of the Rx value returned from workflow

String rx_value = RxIdentifier.rx_value

I now see why I was somewhat confused on the original PR. The name for the value returned from the workflow is rx_value but the value returned is the estimated sex from the genome sequence data. One of the values in the TSV is the actual Rx value (a numeric, decimal value between 0-1). As discussed, the actual Rx value is ok to omit as a workflow output.

Instead of naming the workflow output as rx_value perhaps it should be named to rx_sex_estimate to avoid further confusion?
