Updates to LSC

[mmccarty]

To Do:

• Use Intake
• Updates to SpectralClustering parameters
• xarray reshaping (stack and unstack)
• Remove examples/landsat_spectral_clustering_xa.ipynb
• Remove tifs in favor of intake data sources

I'm slightly confused; in the diffs I don't see any changes to notebooks other than deleting them, even though the description above specifically lists changes.

Also, the intake catalog file presumably needs a newline at the end?

[mmccarty]

Yes, the diffs won't render because I removed all the metadata. You'll probably need to just view the notebook.
examples/landsat_spectral_clustering_xa.ipynb was delete and examples/landsat_spectral_clustering.ipynb was modified.

Intake catalogs do not need a newline at the end, but I can add one.

Looks good, thanks.

@mmccarty I think there is a merge conflict due to the docs PR where I moved this notebook into examples/topics. I'll fix that now...the use of intake should mean there are no issues with local paths or anything like that.

@mmccarty Looks good, thanks!

Hopefully we will be able to avoid specifying the kdims each time and I've bumped a comment on holoviews about this issue here: holoviz/holoviews#2579
