Date facet not included in Gaddel version

[wlpotter]

We'd like to include a facet for a date slider that narrows results based on production date.

Date is in origin/origDate in the @notBefore, @notAfter, or @when dates (as ISO dates). *origin could be in the msDesc for single part mss or msPart if it is a multi-part ms (c.f. #428 )

Date info was not in the example json so I did not include it as a facet. I will add it to the json and add a date slider.

Sounds good! (I'm still working through writing up the issues and will start adding them to the project board as some may need discussion at the next meeting)

For the date facet, we want to model off of https://caesarea-maritima.org/bibl/browse

Added adjustments to date slider, please review

Looks great! We saw a few cases where the dates don't match up with the expected data. I can add some examples to test, but for example setting to 301-368 shows hits from 5th and 6th c.

FYI - just checked and confirmed that all records should have origin date data. I did add one date that was missing
