0.0.3

Added

• Implemented a minimal internal bitreader to inspect HEVC slice headers at bit level.
• Added best-effort detection of first_slice_segment_in_pic_flag for HEVC VCL NAL units, enabling Access Unit (AU) boundary inference when AUD is missing.
• Introduced fallback AU mapping logic based on slice header inspection for streams without AUD (NAL type 35).
• Improved AU association for parameter sets and SEI NALs occurring before the first VCL, assigning them to a practical default AU.
• Added bilingual (ES/EN) error messages in several critical validation paths for better usability across environments.

Changed / Improved

• Refactored compute_au_map() to support dual AU detection strategies:

  • Primary: explicit AUD (NAL type 35).
  • Fallback: HEVC slice header analysis when AUD is absent.

• Enhanced robustness of Access Unit mapping to better handle non-standard or poorly muxed HEVC streams.

• Improved error handling and messaging consistency across commands (info, extract, remove, inject).

• Clarified failure conditions when AUD is required but not present, using explicit and descriptive error messages.

• Improved internal structure and readability of AU mapping logic, preparing the codebase for future HEVC-related extensions.

Fixed

• Corrected AU mapping behavior when VCL NALs appear before any AUD or when AUDs are partially missing.
• Fixed handling of empty or invalid BIN files with clear termination and user-facing error messages.
• Prevented silent failures in matplotlib import by providing explicit diagnostic output.
• Ensured consistent validation of HDR Vivid payloads during BIN injection to prevent invalid cc/pc data from being processed.
