vangel76andClaude Sonnet 5.5 9a0e19aae7 opusenc: memoise the pitch contour correlations ...

The contour search tries 5 base lags times 34 codebook contours times 4
subframes, 680 normalised correlations, but only about 4 x 30 distinct
(subframe, lag) pairs occur. Cache them per call. The values are the same
f64 results as before, so the bitstream does not change (cmp on 24 SILK and
hybrid configurations of 90 s, mono and stereo, speech and music).
