- remove unnecessary checks, restrict Hadamard encoder search (non-normative, bit-identical for CTC)

Detail
- Fix the mis-alignment of rate and distortion during palette coding RD decision.
- Use different weights on luma component cost and chroma component cost.

Enable BDPCM for Chroma for 444.

Add a description of ChromaTS into the software manual.

Replaces 2-dimensional arrays for storing reference samples in
intra prediction with two 1-dimensional arrays. This reduces memory
usage for these buffers from 792KB to 6KB.

This reverts commit 8e16ada0.

- add option to completely disable
- add iparameter to software manual

Use vectors and resize them if needed instead of deleting and
reallocating memory for every picture. This appears to have a
significant impact on decoder run time.

Use PLTRunMode type where appropriate instead of bool since
using vector<bool> creates a number of issues

fix some JCCR related indentation, encapsulation, and descriptive text, add --PYUV to software manual

- refactoring of MatrixIntraPrediction.h/.cpp (merged classes MatrixIntraPrediction and PredictorMIP, removed namespace Mip)
- removed unused variable posBias in function computeReducedPred
- fixed list size in function reduceHadCandList

This reverts commit 9503ca9c

- fixed build error

- Fix for the case that uninitialized or invalid best cost values are referred during search candidate selection
