Add additional information into prerequisite tree

[jloh02]

Some courses have additional information in the prereq text e.g. BT4103

If undertaking an Undergraduate Degree THEN (if in one of the cohorts prior to 2021 inclusive THEN must have completed BT3102 at a grade of at least D AND must have completed BT3103 at a grade of at least D AND must have completed 1 of ES1601/ES2002/IS2101 at a grade of at least D) AND (if in one of the cohorts from 2022 inclusive THEN must have completed BT2101/BT3103 at a grade of at least D AND must have completed 1 of ES1601/ES2002/IS2101/UWC2101% at a grade of at least D)

These are essential texts that should be added, perhaps in the branching logic of sorts. In addition, it seems the AND path compression in this feels wrong but imo OR seems more fitting
