Enables or disables the Ls/Rs band-0 21-tap DC compensation. The caller derives
it from the JOC downmix configuration: only configurations 3 and 4 enable the
filter. When disabled, band 0 keeps the common per-band processing (surround
delay plus -j rotation) instead of being overwritten by the FIR. The delay line
and DC history advance either way, so the flag may change between frames.
Defaults to enabled when never called.
