Add support for 24 and 32 bit .wav's

[L4Vo5]

Apparently those .wav's are always format_code 3?

The conversion is SLOW on long files (like songs).
It requires going through every byte to do the conversion.
So if performance is important, GDScript is just not fast enough for this.

Should fix #7 and #10

i am pretty sure #3 also had a similar issue, this might also fix that

It didn't when I checked sadly. That .wav has a different issue.

Yup, as I say in the readme file of this script, this script will only be necessary until its funcion gets implemented at the core engine, or via GDNative (I think it should be at Core since everything we do here the engine already does it when importing resources but it doesn't at runtime)

Thanks a lot for the contributions and comments!
