DecodeErrorCallback in the Web Audio API has the wrong signature

[CShankland]

Relevant spec excerpt from section 2.1:

callback DecodeErrorCallback = void (DOMException error);

Definition from src/lib/dom.generated.d.ts:

interface DecodeErrorCallback {
    (): void;
}

A related issue is missing disconnect overloads in AudioNode (section 2.4):

    void      disconnect ();
    void      disconnect (unsigned long output);
    void      disconnect (AudioNode destination);
    void      disconnect (AudioNode destination, unsigned long output);
    void      disconnect (AudioNode destination, unsigned long output, unsigned long input);
    void      disconnect (AudioParam destination);
    void      disconnect (AudioParam destination, unsigned long output);

Existing dom.generated.d.ts definition:

disconnect(output?: number): void;
