Tongass National Forest polygon needs to be simplified #104

This polygon is valid, but the rendered GeoJSON is way too big (35MB) and it won't load in the browser.

We need a simplified, but still valid, representation of this place.

A 100 m simplification yields a 7.2 MB GeoJSON and still looks decent given how crenulated that part of the AK coast is. In this screenshot example, the purple is the original, and the yellow is the simplified overlain on top. The value of 100 means that all parts of a simplified geometry will be no more than 100 m distance from the original.
