Add Waveform visualization api

[Iamshankhadeep]

fixes #421.

[JonnyBurger]

TODOs:

• Added new createSmoothSvgPath API - need to document it
• Update the Audio visualization page to mention the new API and give guidance on which API to choose for what (audio vs. music)
• New normalize property was added to getWaveformPortion and not documented. Will result in type error for people who upgrade. What shall we do?
• Better explain examples and maybe copy it over to the Audio visualization page
• Insert new voiceover (I ordered from Fiverr)

@Iamshankhadeep I'm about to dive into AudiVis for my next project; is this good to go, or is there some more work (API or otherwise) needed?

TIA :)
