    Evas ETC1: Use LZ4HC for higher compression ratios
    
    LZ4HC has a higher compression ratio than LZ4 but basically the
    same decompression speed.
    
    The performance cost during encoding is actually still pretty low
    considering how expensive ETC1 compression can be (even at medium
    quality).
