Filters and dropdown

[hellonewman]

The map/table needs filters for users to input their criteria:

• "Open now" compares current day/time to open days/hours
• "Accepts SNAP"
• "Accepts WIC"
  Other filterable items might be added but this will be good to start.

We also need a dropdown for users to select the type of store they are looking for: Supermarket, convenience store, farmers market, or summer food site. This should be a "check all that apply" filter type.

copied from recent PR:

adds basic version of dropdown filters for the map

notes:

• the multi-filter might want different options/more options/correctly spelled options

• the filter for things like wic/snap might be better as individual checkboxes? also I had to test functionality using 'saturday' as the filter rather than things like wic or snap because there is currently no data with 'true' for any of them

• all of it could use a refactor probably, very quickly done
