Color ramps and classification

[gjmooney]

Implementing #173

I started to add automatic data classification and color ramps. I still need to add other classification methods, add it to other render types, and work on the UI a bit.

Looks great!! Tested on the jupyterlite deployment and that works nicely there too

I wondering if it would make sense to have the spinner on top of the entire dialog when fetching and processing the data? With a blurry background blurring the rest of the buttons

Yea we could do that. This comment made me realize there's an issue, if you open the symbology panel before the band data is in StateDb it gets stuck loading. Maybe we should keep the band loading in the panel?

The colormap names are not visible when using the light theme. I guess we should not use CSS variables for those but harcoded white?

Sometimes it stops showing the color ramp that was used for generating the color stops (e.g. when closing the symbology panel and reopening it). I wonder if it would make sense to store the colormap type in the schema so that it's easier for you to restore the state of the symbology panel?

Yea I was debating whether to save that stuff in the schema instead of StateDb but I didn't want to clutter up the schema too much. I'll look into this a bit and see if I can figure out what's happening before we change the schema.
