LFNoise2

A quadratically interpolating noise UGen. This interpolation happens between breakpoints chosen randomly between -1 and +1 at a specified frequency.

The frequency is quantized to the nearest integer division of the sample rate, and changes in frequency are only picked up at the next trigger. In contrast, variant LFDNoise3 has precise frequency and reacts to frequency changes instantly.

'''Note:''' Due to the interpolation, the output values can occasionally extend beyond the normal range of -1 to +1, if the frequency varies in certain ways.
