Bitstream feature name: Palette predictor initialization

Bitstream feature description:

The purpose of the bitstream is to test the functionality of specifying
palette predictor initializers in the SPS and/or PPS.

Slices are coded as I, P and B slices. bit_depth_luma_minus8 is set
equal to 0 and bit_depth_chroma_minus8 is set equal to 0.
chroma_format_idc is set to 1. There are a total of 33 pictures. In the
bistream, the palette predictor initializers in both SPS and PPS are
enabled. The bitstream consists of one SPS and three PPS's:

- The first part of the bitstream contains the first SPS with
sps_palette_predictor_initializer_present_flag equal to 1 and the first
PPS with pps_palette_predictor_initializer_present_flag equal to 0.
Therefore, the pictures in the first part of the bitstream use the
palette predictor initializer signalled in the SPS.

- The second part of the bitstream contains the second PPS with
pps_palette_predictor_initializer_present_flag set equal to 1.
Therefore, the pictures in the second part of the bitsream use the
palette predictor initializers as signalled in the second PPS.

- The third part of the bitstream contains the third PPS with
pps_palette_predictor_initializer_present_flag equal to 1 and
pps_num_palette_predictor_initializer equal to 0. Therefore, the
pictures in the third part of the bitstream use an empty palette
predictor initializer.
