I wanted to test your script, but i get an error while trying to parse a geojson:
Command: ./cli.js Barcelona.osm.geojson > barcelona.obj

Output:

/tmp/geojson2obj/feature-to-geojson.js:124
            geom.coordinates[0][0][2] ? function(cb) { cb(); } : function(cb) {
                                  ^

If you want the geojson that i'm using:

wget https://download.bbbike.org/osm/bbbike/Barcelona/Barcelona.osm.geojson.xz
unxz Barcelona.osm.geojson.xz
