Add default color map for ospsuite plots

[IndrajeetPatil]

As discussed in Open-Systems-Pharmacology/OSPSuite-R#894

What the palette looks like:

library(paletteer)
library(scales)

show_col(paletteer_d("ggsci::default_igv"))

So that, in the code below, tlf::ColorMaps$default (length = 6) will be replaced by tlf::ColorMaps$ospDefault (length = 51):

just out of curiosity: are those magic numbers created randomly or is there any kind of "algorithm" behind?

You can see the algorithm here:

Thanks. Following that link I found the page here with the nice overview of those colour palettes:
https://cran.r-project.org/web/packages/ggsci/vignettes/ggsci.html

Which gives some inspiration for our future extensions :)

If you are looking for a more general overview of color palettes in R, you can see it here:
https://github.com/EmilHvitfeldt/r-color-palettes

It combines palettes from dozens of different packages.

Nice. We should suggest https://github.com/aljrico/gameofthrones as our default palette to @PavelBal 😉
