545	wrong level mapping of zero coefficients in TS residual coding	LiZhang		"In TS residual coding, level mapping is invoked for non-BDPCM coded blocks.
However, the mapping should only be applied to non-zero coefficients. Otherwise, zero coefficients won't exist anymore.

This is also misaligned with the VTM-6.0. 

Suggested changes to the syntax table on TS residual coding:

residual_ts_coding( x0, y0, log2TbWidth, log2TbHeight, cIdx ) {
...
 if( intra_bdpcm_flag  = =  0 '''&& (AbsLevelPassX[ xC ][ yC ] + abs_remainder[ n ]  != 0)''' )  {
 ...
 }
