[semester-upkeep] Date and filename manipulation

[jmuchovej]

Dates are fun! 😂 Really, though, they're kind of a nuisance. We have a few weird things that can change throughout the semester, with respect to dates and room placement.

Tasks

• (🔑 Required) Allow for dates specified in syllabus.yml to override any calculated dates from the autobot.apis.ucf.
• (🔑 Required) If the date follows the meeting pattern, as specified in overhead.yml, then automatically accept the new date – even if it leaves weeks of gaps.
• (🔑 Required) Meetings are unlikely to change (especially if the "rules" are followed – all meetings are specified at the beginning of the semester). However, there are often cases where we either need to resolve name changes or date changes.
  • Within a group's semester, all filenames must be unique, so this resolution becomes a wee easier. Always trust the syllabus.yml's data over what exists on disk.
• (🍜 Nice to Have) Allow for off-pattern meeting days.
• (🍜 Nice to Have) Adapt this for ops meetings as well. @SirRoboto thoughts on this?
