Description
[`filter_features`](https://github.com/mapbox/supermercado/blob/ecc9f5a36c1c8d13872df5bdcbd01621e5f3ab48/supermercado/super_utils.py#L57) decomposes MultiPolygons, MultiLineStrings, and MultiPoints into sub-features, but its output is not valid GeoJSON because these sub-features do not have a `properties`.

Research direction
Start in supermercado/super_utils.py at filter_features, around line 57, and inspect how MultiPolygon, MultiLineString, and MultiPoint geometries become sub-features. Ensure each resulting feature has properties so the output is valid GeoJSON. Done means decomposed features retain or include properties and the existing relevant checks pass.
