File watching fails on MacOS Big Sur beta

[rgm]

There's an issue in JNA that's biting Figwheel too for users on macOS v10.16 / v11 / Big Sur or whatever we're calling it (ie. the new version for Sept 2020 being beta tested right now). The annual increase in security-related lockdowns has introduced a crasher into JNA, which kills barbary, which kills hawk, which kills bin/kaocha --watch.

bhauman/figwheel-main#253

The low-friction temp fix we figured out for Figwheel while this is being sorted out is to tell hawk to start with a :polling watcher instead of a :barbary watcher. It kills battery life since it's no longer using native filesystem change events, but at least it keeps things working while it gets sorted out at the JNA level.

Is there a similar way to allow passing hawk options into kaocha, or, if not, a PR for the same being welcome? Might be a useful add beyond this one temp fix. I think it's in Figwheel to help cope with some Docker-related issues.

@rgm Looks like this has been fixed? thheller/shadow-cljs#767. Adding the ability to pass hawk options isn't a bad idea, so I may keep this issue open for that change.

Oh, I figured out you can already pass options into Hawk: https://cljdoc.org/d/lambdaisland/kaocha/CURRENT/doc/7-watch-mode#configuring-the-watcher
