JVET-AP0092 AHG9: On redundant bits related to string signalling in the CR and NNPFA SEI messages in VSEI TuC [J. Xu, Y.-K. Wang (Bytedance)]

This document proposes the following items:

1. Save byte alignment when there is no type description for a layer in the constituent rectangles (CR) SEI message.
2. Save a redundant bit for signalling nnpfa_prompt_update_flag in the neural-network post-filter activation (NNPFA) SEI message in some cases.

Item 2 discussed.

It was noted that the syntax of the NNPFA extension in the TuC has v4 backwards compatibility issue.

JVET-AP0176 is related to backwards compatibility issue.

Also in 6.2.4

It was suggested to move the while (!byte aligned) syntax to be under the if condition. Agreed to this suggestion.
