1391	cabac_bypass_alignment_enabled_flag: escapeDataPresent is initialised more often than in specification	dominik.wojt	rajan_joshi	"HM-reference software resets the escapeDataPresent flag more often than it is specified in HEVC v2 specification.

In HEVC v2 specification, ""7.3.8.11 Residual coding syntax"" escapeDataPresent is being reset once per transform block.

In HM software 16.4
https://hevc.hhi.fraunhofer.de/svn/svn_HEVCSoftware/tags/HM-16.4/source/Lib/TLibDecoder/TDecSbac.cpp:1395
escapeDataPresentInGroup is being reset every subblock.

This discrepancy can cause bitstream be incorrectly decoded when some subblock other than lastSubBlock has no residuals.
