Rework method of obtaining volume bars
Currently the method of obtaining volume bars can be quite inconsistent, as vorbis formats seem to have values between 16000-17000, and other formats can vary from 0-100 and 0-1000.
We need to either use gstreamer directly to figure out levels or do a much deeper dive into Qt Multiimedia (ex. https://doc.qt.io/qt-5.12/qtmultimedia-multimedia-spectrum-example.html)
