Additional param to get nearest lot

[mudar]

Based on slack discussion:

We could add extra params to GET /v1/lots to return the nearest lot if the current radius returns an empty array. That would probably be a second call by the clients.

• The new param would override radius
• Could either return a single result, or multiple (another limit param?) results sorted by distance.

The /lots endpoint now supports the nearest parameter (int). If specified and an int >= 1; it will return the nearest X lots to the lat/long IF there are no lots found within the radius.
