Port the sample from the omni.ocean extension

CHANGELOG.md

@@ -16,6 +16,7 @@
 - Fix array in-place op (`+=`, `-=`) adjoints to compute gradients correctly in the backwards pass.
 - `wp.sim.Model.edge_indices` now includes boundary edges
 - Allow shadowing builtin functions ([GH-308](https://github.com/NVIDIA/warp/issues/308))
+- Add an ocean sample to the `omni.warp` extension.
