JVET-AC0116 : neural network-based intra prediction with learned mapping to VVC intra prediction modes.

all of the suggestion that is from S/W coordinator are adopted.

1. modify doc/software-manual.tex

2. replace 2D array [64][64] for this MR with vector

3. fix Bug in bitstreamExtractorApp regarding removing APS.

implement JVET-S0219,
in order to implement extraction process that is decided to adopt by JVET_S0219, the equation (32) in the SPEC(JVET-S2001_vG) is needed to integrate. for this, JVET-R0193 and JVET-S0141 item47 is also implemented here.
please refer below meeting note for each aspect.
[JVET-S0219] Enable removal of parameter sets (i.e., PPS and APS) in non-output layer that is not used as reference for decoding of pictures in output layers during extraction process

AHG Recommendation (cleanup): Adopt APS aspect only.

[JVET-R0193] Signal max_tid_il_ref_pics_plus1 value separately for each direct reference layer of a layer, i.e. max_tid_il_ref_pics_plus1[ i ][ j ] for each direct reference layer j less than i, instead of single  max_tid_il_ref_pics_plus1[ i ]

AHG Recommendation (cleanup): Adopt. Text was provided in the contribution, and the authors are to supply the software

[JVET-S0141 item 47] In the general sub-bitstream extraction process, specify the conditions under which an output sub-bitstream is required to be a conforming bitstream such that the value of tIdTarget is specified to be in the range of 0 to vps_ptl_max_tid[ vps_ols_ptl_idx[ targetOlsIdx ] ], inclusive (instead of 0 to 6 inclusive)? (JVET-S0158 aspect 1)

Editor action item: The editor is suggested to include this change.

getSlicePoc() partially duplicates parsing of picture header information. So changes in the beginning of the picture header need to be implemented here as well.

Avoiding allocation of filtered org buffers if temporal filtering is disabled. Also adding missing memory release of m_filteredOrgPic in EncApp::destroyLib

Solution for ticket #1400: Add intermediate picture buffer for filtered data for LMCS to restore towards.

JVET-S0115 aspect 2 (JVET-S0142 item 4): Change the name and semantics of vps_all_layers_same_num_sublayers_flag (to be vps_default_ptl_dpb_hrd_max_tid_flag) to only control VPS syntax without requiring the number of sublayers to be the same for all layers.

Also renamed 'numReorderPics' variables to 'maxNumReorderPics'

JVET-R0251 aspect 1: Renaming sps_XXX_pic_present_flag to sps_XXX_control_present_in_ph_flag for bdof, dmvr and prof.

Removed the macro JVET_R0249_SE_PREFIXES since the changes in this merge request only comprises renaming syntax elements and variables.

from chroma unit to luma unit for multiple SPSs
