[Feature]: Allow playing audio files using a lib:// address

[bubblobill]

Describe the Problem

Audio files need to be accessed using https:// addresses for the URI. Foreign URIs cannot be relied upon to be immutable. With add-ons I can store my audio files locally but I cannot play them.

The Solution you'd like

Extend the use of URIs referenced by audio functions to permit lib:// references

Alternatives that you've considered.

None fit. Might be able to do fancy JS trickery in an overlay, but that seems needlessly complex.
