Add file error reporting

[EamonnMR]

GDScriptAudioImport will fail silently if the load fails, which made debugging a bit of a pain. This adds some logging that indicates if a file load has failed and if so, why. It also returns an empty audio stream to allow the calling script to gracefully continue.

It was by adding this logging that I discovered an unfortunate fact: godot absolutely refuses to let you keep a .wav or .ogg file in your pck, even if you specifically include it in the export settings. The existence of this project suggests that someone has gotten it working though; if there's a workaround for .wav/.ogg export behavior, it's probably worth adding to the readme.

actually they reworked that part and you can keep files in the new 3.3 version as-is using "Keep" as import option iirc

also, the owner of the repo seemed pretty fast to respond to my contribution, they might have missed this one, you could maybe try pinging them
