MacOS Big Sur not detected

[stcharitak]

The library is unable to detect macOS Big Sur (11). A user agent example is the following:
Mozilla/5.0 (Macintosh; Intel Mac OS X 11_1_0) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/88.0.4324.150 Safari/537.36

Does anyone have an update to support this?

I see there is a PR for that: #70

Why is it not merged and released?
