Missing bypass functionality (+dark theme?)

[davis-martin]

Hello, I've been making use of your VCV modules recently and noticed Tuube would fail to passthrough audio when using Ctrl+E bypass on it. After testing and discovering feidah, feidah-S, filtah, pannah, and assprdr had the same problem I thought I'd submit an issue.

I'd also like to request dark theme support if you have the time for it, I really prefer to use modules that support the native VCV dark theming since it's an easy one-click toggle from the View menu.

Thank you for your efforts :)
