feat: Adding ATLAS recommended color wheel (#508)

* Adding ATLAS recommended color wheel

Adding a recommended 10-color palette for ATLAS style. After discussion
within the D&I group in ATLAS, we decided to adopt conceptually the same
offering as CMS recently did, with a 10-color accessible color palette
as a default offering based on https://arxiv.org/abs/2107.02270

* [pre-commit.ci] auto fixes from pre-commit.com hooks

for more information, see https://pre-commit.ci

* Should know better than to think I can push without running the tests...
