    Replace DST1 in ext_tx experiment with DST2 · 49d9730f

    The DST2 is implemented by input alternate sign-flip, followed
    by DCT, followed by output reversal.
    Results are roughly the same, but it should be easier to optimize
    the DST2.
    [Interestingly a mtrix multuiply implementation is about 0.1%
