• shorten the code of the callback call for click event(s)
• fixed the visualizer example to show how to get the 2d caontext of the waveform (to be able to re-use it)

• fix js scope bug in event listener code (that I introduced in v4.1.0)

• added a destroy method to the waveform class, call it when the waveform is not being used anymore to remove the click listener

• all color options now accept a canvas fillstyle value (a hex or rgb(a) color, a canvas gradient or a canvas pattern) and got renamed accordingly, check out the readme for details about fill style values
• fixed a bug where default layout options would not be overwritten by new options
• the click callback interface got renamed to IWaveClickCallback for consistency
• the core options interface got renamed to IWaveCoreOptions for consistency
• updated the example to the reflect the changes mentioned above and make use of the new fill style

• eslint-plugin-import dependency update, to fix JSON5 related CVE-2022-46175

• updated dependencies and removed UMD support, this and future versions will be ESM only

completly rewritten and improved version of the waveform visualizer, using typescript, with a working example using the audio player https://www.npmjs.com/package/web-audio-api-player and date generated using https://github.com/chrisweb/waveform-data-generator
