Add useful built-in colormaps

In addition to the "primary" color maps provided by [`ColorTables`](https://github.com/imagej/imagej-common/blob/c07c5ddf6ee22456eec2ffc7c4c665928ccd4b84/src/main/java/net/imagej/display/ColorTables.java), it would be useful to also provide optimal color maps in the following categories:

* linear (with optimized local contrast), e.g. `mpl-viridis` or the `linear_bgyw` one from [here](http://peterkovesi.com/projects/colourmaps/),
* diverging (with both white or black center values),
* cyclic,
* isoluminant,
* protanopic-deuteranopic and tritanopic versions of the above.

See the [Visualization wiki page](https://imagej.net/Visualization) and http://peterkovesi.com/projects/colourmaps/

Start by reading src/main/java/net/imagej/display/ColorTables.java to understand the existing primary color maps. Then review the linked Visualization wiki page and Peter Kovesi's colourmaps reference. Done means providing the requested linear, diverging, cyclic, isoluminant, and color-vision-deficiency map categories in addition to the existing maps.
