Sample Analytic Vector Tile output

Connects: https://github.com/azavea/osmesa/issues/28

We should generate sample vector tile output to get early integrations testing and iteration going.

Use: `s3://osm-pds-tmp/` that were generated by Seth.

Expected Output:

- Vector tiles at zoom level 12
- All features go into a single vector tile layer named `all`
- Feature `tags` contains `created`, `modified`, `version`, and `type` fields.
- Features contain, highways, waterways, buildings

Some geometries may not represented in the layer and `modified` tag may need to be mocked. I don't believe it can be correctly generated with current vectorpipe code

Start by reading connected issue #28 and inspecting the current vectorpipe code, using the generated data in s3://osm-pds-tmp/. Done means producing zoom-12 vector tiles with one `all` layer containing highways, waterways, and buildings, with the requested feature tags; note which geometries or `modified` values cannot be generated.
