Add streamorder filter to navigation

[dblodgett-usgs]

For any navigation, we should be able to filter on stream order. This is mostly useful for the flowline response, but would be useful in general.

There is a nhdplus.plusflowlinevaa_np21 that has a streamorder column that is an integer. We should be able to return only comids with stream order according to a filter.

The implementation of this could be through two URL query parameters. something like: minimum_streamorder and maximum_streamorder. If only minimum is specified then maximum is assumed to be unbounded, or the max in the dataset and vice versa.

This can be closed once you can add ?minimum_streamorder=2&maximum_streamorder=3 to a navigate request that would otherwise return all data for that navigation from some data source.
