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

- getTrTypes function is moved to TrQuant class

- Implicit transform derivation
- DST-7 is applied horizontally/vertically as long as the number of (luma) samples are less than or equal to 16 in a row/column, otherwise DCT-2 is applied.

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.

This is for the case where JVET_M0464_UNI_MTS is disabled

- all elements of SPSNext are moved into SPS
- syntax elements of SPS are sorted according to draft (as far as possible)
- comments were added where software and draft diverge

calculate and check shifts only when they are actually used

There is a conflict with JVET_M0427_INLOOP_RESHAPER that is triggering a debug assertion that checks that the width is not 1.
