[FEAT] Pre-Requisite Course Filtering

[Al-Saihan]

PrePreReg section could have a filter option, which could enable users to search for courses using "Pre-Requisite courses".

For example:

• User enters, CSE221 as a Pre-Requisite
• PrePreReg shows the courses that CSE221 possibly unlocks: CSE370, CSE321 etc.

Instead of implementing this in the filter modal, I'm thinking of something else.
As we are planning to implement a grade analysis page in the next possible sprint.
We may as well add a course planner mind map interface. And in the mind map. The flow chart will require prereqs to be done before adding a course in the sequence.
