version 2.5.0

What's new:

Improvements:

• Behavior of the onCanvasResize callback is now consistent across different browsers. Changes worth of note:
  1. on fullscreen changes, only a 'fschange' reason will be reported to the callback function - no more redundant 'resize' calls;
  2. the callback function is now executed only when canvas dimensions effectively change from the previous state - for example,
     setting loRes or width to the same value they already have won't trigger a callback;
• Canvas dimensions are now properly updated whenever the container element is resized, not only on window resize;
• audioSource now returns the first audio source connected via connectAudio() method, if no source was provided during instantiation;
• Size of scale labels on both axes is now scaled relatively to the canvas height;
• Added a new demo with only the minimal code required to use audioMotion-analyzer;
• Demo scripts are now loaded as native ES6 modules and no longer require bundling. See the README file for instructions on running the demos locally.
