Create named_places detail view linked from plot obs detail view

[DarianGill]

This has not been prioritized because it's seemingly redundant with existing lat, lng, state, and country information already displayed in the app.

Still, for completeness named_places were added to the api response from vegbank2 in #240 but they are only returned as nested values within the plot observation endpoint for example:

"named_places": [
    {
      "code": "n-us-me",
      "description": null,
      "name": "Maine",
      "system": "region|state|province"
    },
    {
      "code": "n-us",
      "description": null,
      "name": "United States",
      "system": "area|country|territory"
    },
    {
      "code": "TME0863",
      "description": "Maine, Southern Lat:44° 15' 00\" Eastern Long: -068° 07' 30\"",
      "name": "Seal Harbor",
      "system": "quadrangle"
    }
  ],

For this to be implemented we'd also need np_codes for each and a get_named_place endpoint that accepted them and returned additional fields including:

• rf_label
• rf_code
• obs_count (And the ability to filter plot obs by named_place)
• parent_places
  • np_code
  • name
  • convergence
• child_places
  • np_code
  • name
  • convergence

So we could make a view like the original vegbank's:

Or this really long one:
