Please add flac-metadata-bindings

[gabrielhdt]

The library flac-metadata-bindings provides bindings (through foreign function interface) with the libflac to read metadata. The libflac library allows to read metadata and stream information from FLAC music files. I'm using this library in some other personal project in order to read FLAC tags to sort music files in some library.
