Why the need of AudioContext and Analyzer

[nuthinking]

If a Clubber instance can be updated passing the frequencies data, why should we pass in the constructor the AudioContext and Analyzer (they get created automatically otherwise).

Seems to work not passing any context and analyzer, but these get created for apparently no reason.

Indeed there is no reason to create these if not used, I'm preparing a fix, thanks
