Release 4.10.1

Because a few false positives were fixed, this release may see the number of reported issues go down. In pages with lots of very similar elements a performance bottleneck was fixed, allowing axe to finish sometimes up to 10x faster, although for most pages there won't be a difference. Lastly there is a small change to the ancestry selector of elements in shadow DOM. These weren't always guaranteed to be unique. The change means deduplication based on ancestry selectors may not work between 4.10.1 and older versions.
