Description

We should have music and sound effect volume options in the settings menu.

Alternatives & Prior Art

#100 setup the tab system needed to have multiple settings pages. The only thing we will need in addition to that will be slider widgets.

Building the slider will be bulk of the work for this task, but there are some slider textures in the wood and paper assets from the FishFight repo that we can use for the graphic design. We can also probably copy the egui slider for the most part and just swap out the rendering pieces.
