Request enhancement from Springshare for LibCal hours API

[cappadona]

I was able to confirm my original suspicion from #89 that:

1. LibCal only provides hours for dates in the past within the current week
2. LibCal weeks begin on Sunday

This means that our still open from yesterday logic will always return false on Sundays. For the time being I've implemented it in a way that it fails gracefully -- no thrown errors to the public -- but just a heads up that this will lead to potential false negatives for any space that is open beyond midnight on Saturday evenings.

At the moment, we don't have any spaces tied to signage that meet this criteria, at least not for regular hours.

I fully expect that this will not be true during extended hours such as study periods and final exams.

Proposed Solution

Reach out to Springshare support to request that the hours API endpoint provides past hours for at least the past two weeks (or guarantees hours can be returned for today - 1?)
