To update Disclosure index and reports

[gwallison]

• Move disclosure meta table maker to common
• Color values based on source (FF or OpenFF)
• Show important flags
• Explain why no mass was calculated, in those disclosures.
• Include explanation tables (not directly in the html)
• Can I make column-hiding work?
• Can I make floating header work?
• In DI of somewhere, make an API entry that will show and link to all disclosures
• For DI, because it is so big, point to (and make) county-based versions.
• Does it make sense to store the tables separately and 'include' the in a template?
