Add the 6 color and 8 color sequence for the Petroff color cycles #30060
Description
The 6 color sequence by Petroff is not just a truncated 10 color sequence. It has distinct colors. You can read thrombus here and make a custom color sequence https://arxiv.org/abs/2107.02270.

@timhoffm That was my memory (and if I had dug back further into Issue #9460 I would have seen #9460 (comment) and it would be obvious, so thanks for the reminder on that), but it seemed weird given the discussions we had with @tacaswell on mpetroff/accessible-color-cycles#1 that we didn't add the 6 and 8 color sequence at the same time in PR #27851 so I thought I might be mistaken.
The colors for the 6, 8, and 10 sequences:

I finally finished the manuscript and have the pre-print posted (and the analysis code). The final results are:

make a custom color sequence
Is there a reason to not support the 6 and 8 sequence as well? I assume not, given that the style sheets have 8 color styles. Would a PR be of interest here?
