Task 1-2: Benchmark HUC Query of NWM Gridded Zarr Output

While the most likely query pattern for gridded output data will be by HUCs, the performance of the Zarr library relative to the size of the query needs to be benchmarked. To that end, we will perform this benchmarking for several HUC 8, 10, and 12 regions. These will also be recorded as a sample documentation notebook in the project repository.

Start by locating the project's NWM gridded Zarr output access path and the existing notebook conventions. Benchmark HUC 8, 10, and 12 queries across several regions, and record the results in a sample documentation notebook in the repository.
