Add new OT global raster datasets

[mdpiper]

OpenTopography has made available two more global raster datasets:

• EU_DTM (DTM 30m)
• GEDI_L3 (DTM 1000m)

The Topography data component should be updated to access these new datasets.

@mdpiper - EU_DTM (Continental Europe Digital Terrain Model 30m) dataset's boundaries, Europe itself, does not include test point location. So it returns an empty dataset and fails tests.

We may either skip this test(s), or use different test point area, or handle some specific test case for this respective dem, like this:

92 | CENTER_LAT, CENTER_LON = (47.0, 10.0) if dem_type == "EU_DTM" else (40.0, -105.0)
