Copy the periodicWave data into a shareable buffer. Add a SetBuffer call to send the buffer data to the OscillatorNodeEngine. Call into blink's PeriodicWave implementation to generate bandlimited tables bracketing the desired frequency and interpolate the output data from them. Change the PeriodicWave constructor to only take one length, since both arrays must be the same size. Change OscillatorNode's SetType to throw INVALID_STATE instead of NOT_IMPLEMENTED if js tries to assign type = 'custom' directly.
