pbf output results in "Error: Unimplemented type: 3" errors across clients

[tvogt]

using

tippecanoe -e routes (mydata.geojson)

to generate a directory of *.pbf files results in "Error: Unimplemented type: 3" error messages in both openlayers and leaflet.js

the same datasource turned into *.pbf using maptiler works just fine, so it's not the data.

even in Mapbox GL it errors out:

Figured out after much searching that this is probably indicating a zipped pbf file. That kind of should at least be mentioned somewhere.

Tippecanoe generates gzipped tiles by default because that is what Mapbox uploads and clients expect. You can use --no-tile-compression if you don't want compression.

[tvogt]

As mentioned: This should be described better and/or the error message adapted. It took me a lot of searching to figure that one out.

Thanks. I'll add a reference to that error message in the README.
