   libavfilter/showcwt: fix OOB write for DU/RL position init
   In config_output() for direction=DU/RL, the position
   is initialized to s->sono_size, which equals h or w
   when bar=0. That position is later used as an
   in-bounds pixel coordinate without clamping in draw(),
   causing writes past the end of the output planes.
   
   Repro:
   ffmpeg -f lavfi -i sine=frequency=1000:sample_rate=44100 \
     -filter_complex "[0:a]showcwt=s=640x512:bar=0:direction=du[v]" \
     -map "[v]" -frames:v 1 -f null -
   
   AddressSanitizer: heap-buffer-overflow ... WRITE of size 1
   
   Initialize and wrap the DU/RL position to sono_size - 1
   (or 0 when empty), preventing out-of-bounds row/column
   writes when bar=0 while preserving existing slide behavior.
