- Previous name: Reduced Secondary Transform (RST)
- The parameter, LFNST, should be added in cfg file for enabing LFNST, i.e. LFNST = 1

Added 'FastMIP' encoder config parameter, removed condition on intra period and picture height in IntraSearch.cpp.

- also adds documentation for ReWriteParamSets parameter

keep max TU in #define for possibility of keeping the parameter

TU max/min size are constants in the VVC draft. Reflecting this in the software.

Speed-Up for ISP when JVET_M0464_UNI_MTS is enabled. It can be enabled/disabled with the config. file parameter ISPFast.

When enabled,
-it merges all full RD intra mode lists into one,
-it tests fewer non-DCT-II transforms if ISP is likely to become the best mode and
-it stops testing intra modes for an ISP split if all sub-partitions obtained a zero-cbf.

Results in CTC:

AI -> 0.04% loss, EncT = 97%, DecT = 100%
RA -> 0.01% loss, EncT = 99%, DecT = 100%

AMVR (formely IMV) now has only one mode, which used to be mode #2
- remove SPS imv_mode parameter
- remove encoder configuration for mode #1 (mode #2 replaces mode #1)
- adapt config files to refer tp mode #1
- rename SPS syntax elements and access functions to AMVR

Note: IMV to AMVR renaming in other parts of the software should be done by proponents.

JVET-M0247 1. Add early termination and encoder search method. 2. Only enable it for RA configuration.

change default param value of C[b,r]QpOffsetDualTree from 1 to 0, change value of C[b,r]QpOffset from 0 to 1 in CTC configs
