RADEX: Update to be consistent with treatment arms.

[cicdguy]

Please update logic for ADEX starting with records where PARCAT1 = INDIVIDUAL. Currently subjects are randomly assigned to Drug A or Drug B (in PARCAT2) but instead the assigned drug should be consistent with ADSL. ARM.

The table below represents the metadata that should drive how the random data is generated. Feel free to rewrite or simplify current code as needed.

PARCAT2	Arms this drug applies to	Single Dose (EXDOSE)	Dosing Schedule
Drug X	Arm A or Arm C	10mg	Daily
Placebo	Arm B	0mg	Daily
Drug Y	Arm C	50mg	Every 7 days

Please also update AVISIT/AVISITN to be by CYCLE X (1, 2, 3,....). You can assume each cycle is 28 days. Note AVISTIT/AVISITN should not include SCREENING and BASELINE.

Please also add missing variables:

AVALC
ANL01FL

Please open up a PR once the randomization for PARCAT1 = INDIVIDUAL is ready. Then can move on to the PARCAT2 = OVERALL records.
