Remove unneeded waterway='' check ( #1377 )
...
This PR removes an unnecessary check in water.yml.
generated SQL before:
```
SELECT CASE
WHEN waterway='riverbank' THEN 'river'
WHEN "waterway" = 'dock' THEN 'dock'
WHEN "water" = 'river'
OR "waterway" = 'riverbank'
THEN 'river'
WHEN "waterway" = '' THEN 'lake'
ELSE 'lake'
END;
```
generated SQL after:
```
SELECT CASE
WHEN waterway='riverbank' THEN 'river'
WHEN "waterway" = 'dock' THEN 'dock'
WHEN "water" = 'river'
OR "waterway" = 'riverbank'
THEN 'river'
ELSE 'lake'
END;
```
The `waterway=''` test is purely redundant because it returns the same value as the fall-through ELSE case: `lake`.

Water layer river mapping bug fixes ( #1182 )
...
This PR is a bugfix for the `water` layer.
* `waterway=stream`, `waterway=river`, `waterway=canal`, `waterway=ditch`, and `waterway=drain` are all linear features, not area features. Thus, these objects are being unnecessarily mapped into the `osm_water_polygon` polygon table, and this PR removes these unneeded mappings.
* The combination `natural=water` + `water=river` is the most popular tagging for river areas. However, the current mapping causes rivers tagged in this way to be rendered in the vector tiles as a `lake`. This PR adds a check for the `water=river` tag and tags both variants of river areas as `class=river`.
`natural=water` + `water=river` river mapping:
`waterway=riverbank` river mapping:
Lake mapping for a `natural=water` (with no other tagging):

Manage field mapping in SQL declaratively
...
Simplify some of the OSM->OMT field value mappings using declarative syntax.
This approach is not for all cases, but in many it removes
the need of storing the same field in both the .yaml and .sql files.
