Changes made
mp4chapterlist.h
• Added (MP4::File*) overloads for read, write, remove
• Replaced broken class File; forward declaration with #include "mp4file.h" (fixed a subtle C++ name-resolution linker bug where Atoms(File*) resolved to MP4::File* instead of TagLib::File*)
mp4chapterlist.cpp
• Refactored: path-based overloads are now thin wrappers that delegate to file-based overloads
• File-based overloads construct Atoms locally — no Atoms* in the public API
• Removed chplHeaderSize = 9 constant; replaced the minimum-size guard in parseChplData with a correct 5-byte check (the old constant was version-1 specific and would reject valid version-0 atoms)
mp4qtchapterlist.h
• Added (MP4::File*) overloads for read, write, remove
• Removed Atoms* parameters entirely from the public API
mp4qtchapterlist.cpp
• Same refactor: path-based overloads delegate; file-based overloads construct Atoms locally
• Added empty-chapter guard: write(MP4::File*, {}) delegates to remove(file) instead of writing a 0-sample chapter track
tests/test_mp4.cpp
• Added testChapterListFileAPI and testQTChapterListFileAPI — exercise the full write/read/remove cycle via the file-based API
• Updated test bodies to use the simplified (MP4::File*) API (no MP4::Atoms construction in test code)
