Allow decoding aiff using ffmpeg.dll

- Add aiff to Settings - Formats. Use ffmpeg.dll as Decoder.
- Slightly increase height of listViewFormats in order to avoid
  initial scrollbars in Settings - Formats, after aiff has been added.
- In order to decode AIFF files using CUETools, ffmpeg 6.0 dlls
  need to be copied to plugins\win32 or plugins\x64 as usual.
- Resolves #298
