Index dates for Ephemera Folders

[tpendragon]

Acceptance Criteria

• There's a years field in the solr document that has all of the years in an array that should match.
• There's a display_date field in the solr document that is what will render in the record page.
• There's an oldest_year field in the solr document that is the oldest year in the range.
• There's a newest_year field in the solr document that is the newest year in the range.

Record A: "1920 - 1960"
Record B: "1930 - 1945"

If we use the oldest date for oldest to newest, and the newest date for newest to oldest, we get this:

Sort date ascending: Record A, Record B
Sort date descending: Record A, Record B

Implementation Note

The suffix isn't defined above, part of the ticket is figuring out which suffixes are appropriate for each field.
