Improvements on Fitness Overlay Rust Video Project

## Customizable Video Overlay Layouts Looking for a developer to add layout customization options to an existing video overlay tool. ### Requirements * Allow users to customize which metrics are displayed and in what order via CLI arguments. * Add CLI toggles to enable/disable visual widgets and overlays. * Introduce a configuration/options structure to manage layout settings cleanly. * Validate conflicting CLI options and provide user-friendly warnings where appropriate. * Maintain current behavior as the default when no options are provided. * Add unit tests covering configuration parsing, layout behavior, and overrides. * Update example previews/screenshots demonstrating the new customization features. ### Deliverables - --metrics cli flag - comma separated override on the on-screen metrcis row (e.g --metrics pace,hr,distance) - --widgets optional widgets like elevation and hr zones on differenet workouts, right now outdoor run doesn't have HR or elevation, hike / biking also not - unit tests for this whole project to ensure everything works well - Manually test all the flows if possible & send over example videos of each of these & testing manual input flows - Improving the documentation by adding practical non llm-generated examples to YT vids There's a potential for follow-up to convert this to a SaaS (Mobile app connecting to Strava or Garmin / Web App)
