WLED-Manager v0.0.3

Introducing WebAudio

WebAudio3.mp4

Attention

All this is still pre-alpha-state. If you want to test it, make sure you set IP, PixelCount, Color and Frequency-Band (click one of the equalizer's bars) !before! you click play. Also stopping and replaying is currently resulting in multiple Senders.
When it hangs, just restart the app.

Everything is done without a state-management-lib.
After I choose one, IP and PixelCount can be retrieved automatically.
