Terrain using multiple .usd files

[SourabhPrasad]

Hi,
I want multiple USD files as terrains, but the TerrainImporter only accepts one USD file path. Can multiple USDs be provided to the TerrainImporter, or can multiple meshes be combined into a single mesh programmatically?

I haven't done this myself, but looking at the documentation here: https://isaac-sim.github.io/IsaacLab/main/source/api/lab/omni.isaac.lab.terrains.html#omni.isaac.lab.terrains.TerrainImporter.import_usd

It looks like each time you import a USD file as the terrain it will only import the first mesh in the USD scene. From there, each imported terrain is added to a key value dictionary, so it seems like you should be able to call 'import_usd' more than once.
