v0.3.0

Release v0.3.0

New Features:

• Dataset extract command (extract by class, images-only, labels-only modes)
• Dataset analyze command (comprehensive dataset statistics and visualization)
• Dataset resize command (batch resize YOLO datasets with auto structure detection)
• Colored logging output with colorlog integration

Major Fixes:

• Fix Windows encoding issues in subprocess and file operations (UTF-8)
• Fix IMAGE_EXTENSIONS export bug in all (was object, now string)
• Fix dataset merge duplicate handling for same-name different-extension files
• Fix image crop single file support

CLI Improvements:

• resize: add --split for dataset mode, support upscaling small images
• visualize: replace --train/--val with --split, auto-detect single file
• synthesize: add annotation_format support (obb/hbb), fix memory issue
• Remove viz-hsv command (keep underlying code)

Breaking Changes:

• Dataset merge: removed handle_duplicates parameter (always rename)
• Extract: use class IDs instead of class names for precision")
