[chloe-crews]

Description:

This PR introduces additional functionality in the RainbowGrades system to provide clarity for students regarding assignment statuses. The feature improves the hover text for assignments with a "bad status" by providing specific details regarding late penalties or automatic zeroes.

Changes:

• Introduced two new variables: penalty_per_day and automatic_zero.
• Applied penalty logic for deductions based on the number of late days.
• Created dynamic hover text to display details about penalties or automatic zeroes for assignments.
• Enhanced the TableCell constructor to compute the final score and generate hover text.
• Updated the rendering logic in the output() function to handle cells with penalties or automatic zeroes more effectively.

---

Why:
This feature improves transparency for students, helping them understand why they received a penalty or automatic zero, thereby reducing confusion about grades.
