Constant high CPU usage by the UI

[laurigates]

At least on my system, running Manjaro Linux, the soundsense-rs UI manages to keep two CPU cores at 100% at all times.

Same for my system, both on Manjaro and on Windows 10, on Windows 10 though it only does this when using the debug executable.

I also find that the CPU usage is absolutely excessive on Xubuntu (60-70% even with 6 cores, and the cores are fast), and this is even when the game isn't running.

The culprit behind this looks like a spawned process called WebKitWebProcess 7 16.
