seaborn palettes added

Relevant to discussion in https://github.com/JuliaPlots/Plots.jl/issues/2510

I did not add screenshots yet, but will do if needed (some screenshots can be seen in https://github.com/JuliaPlots/Plots.jl/issues/2510)

[mkborregaard]

Great. Should we add the color palettes to PlotUtils instead and just use them here? And yes, screenshots in the readme for discovery would be good

[isentropic]

Where should I upload the screenshots? The images in the readme.md file are pointing to some https://raw.githubusercontent.com/ like link, perhaps screenshots were put in some issue, or may I create a directory with screenshots?

[mkborregaard]

Yes, a classic trick is to upload them in an issue comment - you don't even need to submit the comment to get the url

@mkborregaard I added the screenshots and the default color gradient seaborn uses. The gradient colorscheme is subtly different from default fire, it is called rocket but it looks much better to me. Justification on why these colors look better is found in the first paragraph here Personally, I would want to put seaborn_deep (default) theme higher on the theme order, as it is widely used in python community and has some fame already. Additionally, just wanted you to know that screenshots are missing pi, I could not get around it as much as I tried with GR backend. It works with PyPlot but the plots themselves look somewhat different then.

@mkborregaard I'm having trouble passing "Pull Request Labeler" at this point I'm not sure if it is on my end

Don't worry about the labeler - that looks like something on our end.

With https://github.com/JuliaPlots/PlotUtils.jl/pull/87 we will be able to use all palettes from https://github.com/JuliaGraphics/ColorSchemes.jl. So I suggest submitting a PR to ColorSchemes with the seaborn palettes instead.

Seaborn is now available via ColorSchemes
