  1. chroma-encoder: Add NTSC narrowband Q encoding 

    Adds a new chroma-mode, 'narrowband-q' to low-pass the Q
component.  Obsolete, but interesting for testing.

  2. chroma-encoder: Add NTSC-specific chroma component filter 

    Change the filter used in the wideband-yuv/yiq modes to
one suggested by Clarke for NTSC.

Small PSNR improvement, up to 0.03 dB.
