Currently, for each USUBJID/QSTEST combo, QSORRES is the same across each visit. This does not make for exciting data.

Update derivation so that eachUSUBJID/QSTEST combo has random QSORRES at each VISIT.

Also use this issue to fix qs_ophtha code so that it doesn't depend on an existing qs dataset (as we have deemed we do not need that)
