feat: new speed input step + manual inputs

[cdrani]

Changes

• Step for Slider updated to 0.001 for finer control, though this now comes with a slight delay of 50ms so the speed is not updated too often when user is just sliding around back and forth. Without the delay, Spotify occasionally will sputter and show an alert about loading the song from a local file.
• Replace the static Track & Global Speed Indicator (originally span) to an input for user manual input of speed values such as 0.982.
• Update the conversion factor (from 100 to 1000) for the speed value used in the share url. For EX: https://open.spotify.com/track/2w4yylkuKugYjEVhwKc0OD?ch=10-60-982-1, 982 would be the speed of 0.982.
