Add av_sat_sub32 and av_sat_dsub32 as the subtraction analogues to
av_sat_add32/av_sat_dadd32.
Also clarify the formulas for dadd32/dsub32.

When decoding to downmixed mono, don't put the channels out of phase,
as they will cancel out and create audible artifacts. (See
RFC 8251 sec. 10.)

Hi James, thanks for reporting the issue. There's indeed a problem
