[sound-juicer] Use libdiscid read_sparse()

[Christophe Fergeau <teuf src gnome org>]

commit 1a55823d38bf450d1280e6c6842cdaa19e7ea5bb
Author: Johannes Dewender <gnome JonnyJD net>

    Use libdiscid read_sparse()
    
    read_sparse is available starting with libdiscid 0.5.0.
    Using read() started to be slow with 0.3.1, since
    now ISRCs and the MCN are read by default.
    We now only read what we need.
