Example of generating a quantized mesh from DEM tile

[fullonic]

Hey @kylebarron!

I'm exploring stacks to generate a quantized mesh from a DEM and I would like to try your library pydelatin & quantized-mesh-encoder. I would like to know if you could provide a small example of converting the DEM tile (opened with RasterIO) into a quantized mesh. Would be that possible?
I can convert the DEM into a NumPy array using the RasterIO, but I can't understand well the next steps to prepare that array to feed pydelatin.

Thanks!

BTW, great work you have done with your tools and contributions to the COG ecosystem 😃

I'd look at this function in dem-tiler, and this bench.py script.

Note that I think imageio.imread might have a different axis order than rasterio; I can't remember off the top of my head

Thanks, @kylebarron! Once I start working again with meshes I will have a look at that. Cheers!
