Typos and variable fixes in palette related text

1. In 8.4.5.3 and below equation (438):

The ( nCbW x nCbH ) block of the reconstructed sample array recSamples at location ( xCbComp, yCbComp ) is represented by recSamples[ x ][ y ] with x = 0..nCTbW − 1 and y = 0..nCbH − 1, and the value of recSamples[ x ][ y ] for each x in the range of 0 to nCbW − 1, inclusive, and each y in the range of 0 to nCbH − 1, inclusive, is derived as follows:

The variable nCTbW should be replaced by nCbW

2. num_signalled_palette_entries is a variable instead of array. The following three places need to be fixed:

• In equation (181): for( i = 0; i < num_signalled_palette_entries[startComp]; i++ )

• Above equation (450): If treeType is equal to DUAL_TREE_LUMA, the following applies for i = 0..num_signalled_palette_entries[ startComp ] − 1:

• Above equation (452): Otherwise (if treeType is equal to DUAL_TREE_CHROMA), the following applies for i = 0..num_signalled_palette_entries[ startComp ] − 1:

The three arrays should be replace by variable num_signalled_palette_entries

Good catch, thanks!

This will be fixed in first verison of D10.
