#1512 new defect

Mismatch VTM/spec on locSumAbs derivation (Range Extension)

Description

When sps_persistent_rice_adaptation_enabled_flag == true, locSumAbs may be updated with HistValue variable according to proposal JVET-W2005-v1.docx.

In VTM : when sps_rrc_rice_extension_flag == false and sps_persistent_rice_adaptation_enabled_flag == true, decoding is made using deriveRice function (see ContextModelling.cpp). This function calls templateAbsSum function, which does not use HistValue.

Another function (templateAbsSumExt) seems to make similar computations but with the use of HistValue. Maybe this is this function that one would call.
