v2.8.1 cannot render tube

[skemaikin]

HI!
I have a test table with the LINESTRINGZ geometry. When I trying to run the utility I have got an error:

> docker run --rm -v $(pwd)/output:/app/output -it geodan/pg2b3dm:2.8.1 -h 192.168.0.250 -p 5432 -U postgres -d postgres -t test -c wkb_geometry

...

Creating tile: 0_0_0.glb  Unhandled exception. System.InvalidCastException: Unable to cast object of type 'Wkx.Polygon' to type 'Wkx.PolyhedralSurface'.

   at pg2b3dm.Program.Main(String[] args) in /src/pg2b3dm/Program.cs:line 25

The table test has only columns: ogc_fid and wkb_geometry.
How to run pg2b3dm correctly to create the tube?

Hi,
different Z works perfectly.
Waiting for #164
