feat: add frame-sampling options for flash/RAM budget control
Add --frame-start / --frame-end to restrict the frame range, and --frame-step / --frame-count (mutually exclusive) to decimate within that range. Kept frames are re-numbered contiguously from 0000 so LVGL's sequential player never sees index gaps. Interactive menu gains a matching "是否抽帧" step; CLI and menu both display a human-readable sampling summary before conversion starts. Bump version to 0.3.0.
