Add FFFA to magic bytes for MP3. Fixes #10

This resolves the problem for me with mono-channel MP3 files. Please let me know if any changes are required, e.g. for code style. Thanks.

Some types of MP3 are not matched

Hi, I have a couple of .mp3 files which are not matched in my testing. It seems the magic bytes can change depending on channels and bitrates of the files....

I get the following when trying to build/run any of the demos. ``` $ go mod tidy .... go: finding module for package github.com/xlab/linmath-go/linmath github.com/vulkan-go/demos/vulkancube imports github.com/xlab/linmath tested by github.com/xlab/linmath.test...
