Linux: noble error -- adapter state unauthorized

[jdpigeon]

Node doesn't have cap_net_raw privileges, so it can't control BLE advertising.

Unfortunately, unlike Muse LSL, running the command sudo setcap 'cap_net_raw,cap_net_admin+eip' $(eval readlink -f which node) doesn't seem to fix the issues. It's likely we've got a situation like the one described here noble/noble#619, where the electron rebuild step kind of obfuscates the node binary we're trying to use.

Another relevant issue: noble/bleno#282 (comment), need to give local electron binary in node_modules setcap access: sudo setcap cap_net_raw+eip node_modules/electron/dist/electron

However, this leads to another issue: electron/electron#4583, caused by Linux disabling shared libraries after changing setcap privileges

I think the smartest thing to do here would be to find a platform-specific way to switch to using purely web bluetooth on Linux. It's already the strategy we're going for on Mac and, though it's not there yet, there's a much greater chance of web bluetooth being supported on Linux than Windows: https://www.espruino.com/Web+Bluetooth+On+Linux

Fixed in #10

Note: we've decided to go with web bluetooth instead of trying to get noble working
