Account for "QC_R_leftover" in passed_wells

[joeyshuttleworth]

Description

The "passed_wells.txt" file outputted didn't account for QC.R_leftover, so these values would have to be checked manually. Now passed_wells only contains those wells which pass QC.R_leftover for the QC/staircase protocols (args.D2SQC).
