1244	software/spec mismatch for APS chroma present flag from R0433 integration	taoranlu		"There is a software/spec mismatch related to APS chroma present flag in current VTM master from the integration of R0433 (MR1767).
In VLCWriter.cpp (and corresponding VLCReader.cpp), when signal the LMCS APS, the condition '''if (pcAPS->chromaPresentFlag)''' should include the signalling both of the sign and abs of lmcs delta crs. In current VTM, only the abs is inside the if condition and sign is left out of the if condition.

Spec:
  if( aps_chroma_present_flag ) {	
    lmcs_delta_abs_crs
    if( lmcs_delta_abs_crs > 0 )
      lmcs_delta_sign_crs_flag	
  }
