Addresses editorial feedback from Yannis, Maryla, and Thomas

Done

• reserved_zeros: Changed "Will be set to zeroes" to "Shall be set to zeroes"
• obu_start_code comment: Fixed 0x01 to 0x000001 to match the 24-bit field width
• hdr_wcg_idc table (value 2): Replaced confusing "Both HDR and WCG are to be indicated in the stream" with "The video stream is both HDR and WCG"
• HDR definition: Replaced vague "EOTF higher than BT-1886" with reference to BT-2100 HDR transfer functions (PQ or HLG)
• Bibliography: Added BT-2100 entry and updated all BT references to use formal ITU-R citation format with version and date

Still to be discussed / done

• Simplify hdr_wcg_idc table entries 0 and 1: Remove "container" language per Maryla's suggestion (e.g. 0 = "A video that is neither HDR nor WCG, i.e. an SDR video", 1 = "A video that is WCG but not HDR")
• format_identifier hex notation: Optionally add hex value (0x41563031) alongside the ASCII 'AV01'. Further thoughts on this?
• obu_size recommendation text: Currently says "easy conversion to MP4" but applies to MP4 and Annex B, wording could be broadened

• format_identifier hex notation: Optionally add hex value (0x41563031) alongside the ASCII 'AV01'. Further thoughts on this?

I find it more precise and convenient to write both representations. Not a big deal either way.

• obu_size recommendation text: Currently says "easy conversion to MP4" but applies to MP4 and Annex B, wording could be broadened

I agree. Maybe even explain why exactly the conversion is easy.
