expand magic byte detection for common file formats

Browse Source 
Add detection for:
- Images: BMP, TIFF, ICO
- Video: MP4, WebM, FLV, Matroska
- Audio: MP3, FLAC, OGG
- Documents: MS Office OLE (DOC/XLS/PPT)
- Executables: PE (EXE/DLL), ELF, Mach-O, WASM
- Archives: BZIP2, XZ, ZSTD, LZ4, 7z, RAR
- Data: SQLite

This improves REQUIRE_BINARY enforcement by detecting more
recognizable formats that should be encrypted before upload.
