[Enhancement]: Performance benchmarking

[tomvothecoder]

Is your feature request related to a problem?

We should do performance benchmarks with xCDAT across different workflows and data types/sizes.

Examples include (WIP):

• High resolution data

Additional context

Two part problem with performance:

1. User needs to chunk their datasets appropriately for optimal performance, based on the shape of the data
   • This is often the bottleneck for most users. Not trivial to understand the optimal chunk sizes.
   • Also setting a cluster is better for performance monitoring, but another barrier to entry.
   • Is there a general way to chunk across different datasets of varying sizes/dimensions?
2. Is xCDAT optimized for work on these chunks? -- We use Xarray APIs for core operations (e.g., grouping), which operate in parallel on Dask Arrays
