Add more timestamps, variables to example data

@maxrjones I would be interested in trying to do this if it is ok with you (or we could pair) - looking at https://developmentseed.org/geozarr-examples/examples/04_multiscales_as_WebMercatorQuad_ZarrV3.html it seems like, for each new time step, we would need to :

1. add append_dim to template.to_zarr(...)`
2. Write to the subsequent time index for the new data, za[1, y_start:y_stop, x_start:x_stop] = tile, za[2, y_start:y_stop, x_start:x_stop] = tile...

but I'm probably missing a step or 2 without trying it 😅

I think rather than using append_dim(), you could construct a dataset with multiple time steps in memory since these are all pretty small. It may be as simple as changing ds = xr.open_dataset(input) to use open_mfdataset(...) with two adjacent NetCDF files.

That makes sense, I was just wondering if for continuous appending, what would be the set of necessary operations based in your example, but perhaps that is overkill for what is currently needed - is that what you are thinking?

makes sense, yes append dim would work for continuous appending to a web-optimized zarr. at the same time, it's probably not necessary for Hanbyul's request.
