Expand DEMs available via OpenTopography API

Suggestion: Since you are already have integrated the OpenTopography Global Datasets API, you could expand your options to include more of the 14 different DEMs available. At the moment only SRTM is offered in BlenderGIS, but it's a quite old dataset and does not provide full global coverage. You may consider offering the COP30 (Copernicus Global DSM 30m) DEM by default and/or allow users to select which dataset they wish to use from a list.

Available datasets are described here: https://opentopography.org/developers & https://portal.opentopography.org/apidocs/#/Public/getGlobalDem

There is also a USGS 3DEP API that offers additional data coverage over the United States: https://portal.opentopography.org/apidocs/#/Public/getUsgsDem
