Update Lab Grading Criteria Metadata

[kaz462]

Grading Criteria Metadata NCI-CTCAEv5

1. From lab_grading/assumptions-made-when-grading:

   For BASE to be abnormal we compare it with the Upper Limit of Normal (ULN) ANRHI, i.e. BASE > ANRHI

   • I encountered a situation where ANRHI differs within a subject and lab test due to data from different lab vendors. Should we consider changing the use of ANRHI to BNRIND when determining whether the baseline is normal/abnormal?

2. Some CTCAE grade definitions contain two sets of units, but only one is provided in the current grading metadata. For example, TERM=Hypoalbuminemia has only one row for unit = g/L, so it's not be able to grade for unit = g/dL can we add more rows to the metadata to cover different units?
