Perceptibly uniform luts

[Tom-TBT]

What this PR does

I added perceptibly uniform LUTs. I started with the LUTs from the viridis family that I found in Fiji, but I extended it to other LUTs used in R: https://github.com/sjmgarnier/viridis

• The LUTs viridis, magma, inferno, and plasma were created by Stéfan van der Walt (@stefanv) and Nathaniel Smith (@njsmith). presentation of viridis by their authors at SciPy 2015
• The LUT cividis, a corrected version of 'viridis' for color vision deficiency (Nuñez, Anderton, Renslow 2018, https://doi.org/10.1371/journal.pone.0199239)
• The LUTs mako and rocket created for seaborn (https://seaborn.pydata.org/tutorial/color_palettes.html#perceptually-uniform-palettes)
• The LUT turbo developed by Anton Mikhailov to address the shortcomings of the Jet rainbow color map such as false detail, banding and color blindness ambiguity. (https://ai.googleblog.com/2019/08/turbo-improved-rainbow-colormap-for.html).

Testing this PR

1. required setup
   An OMERO.server

2. actions to perform
   Add the new LUTs to OMERO.server/lib/scripts/luts

3. expected observations
   The LUTs become available for all tools (but there is no preview of the LUT intensity from the dropdown lists):

• OMERO.iviewer
• OMERO web image viewer + preview tab
• OMERO.insight
• OMERO.figure

1. background for understanding this PR
   The viridis LUT family have been created with perception uniformity as criterion. They are the standard of matplotlib for some time now and are also packaged with Fiji. I think it would be good for users to find them also by default in OMERO.
   The cividis is the colorblind adjusted version of viridis which also has been integrated in Fiji (https://forum.image.sc/t/new-lut-for-fiji-cividis/7467).
   Seaborn also offers two perceptually uniform LUT, mako and rocket, part of the "viridis" package for R.
   Finally, turbo is an alternative to jet that is also more colorblind-friendly and gradual.

2. what this PR assists, fixes, or otherwise affects
   This will package new LUTs with OMERO.server. The LUTs will become available for other OMERO components (web, iviewer, figure, insight) but will not display preview until related PR are merged and deployed.

Added the include label so this will get included in the server merge-ci deployment for testing...

In webclient Preview panel and webgateway viewer, these LUTs are all showing up (without preview png) and are working fine:

Same in Figure:

Same about the iviewer:

And the default omero-web viewer:

LUTs work in clients and don't cause any issues
The preview png is missing as expected - due to be fixed elsewhere
