    Remove deny(warnings) from the toplevel src/lib.rs
    
    This got moved from librsvg_crate/src/lib.rs, where it was presumably
    because we didn't want warnings in the public API crate.  Now that
    we have a single crate, however, this can create warnings on
    architectures which we don't test in the CI.
    
    Specifically, this was causing this warning-as-error in
    gnome-build-meta for aarch64:
