Fix output of bit and tool statistics. If RExt__DECODER_DEBUG_BIT_STATISTICS and RExt__DECODER_DEBUG_TOOL_STATISTICS are enabled, the decoder throws and exception as size of enum CodingStatisticsType and the size of the statNames array don't match. Further, the order of the enum has to match the order of the labels. Also, the bit counter for JVET_L0283_MULTI_REF_LINE was missing.
