Overflow when using Sinc Interpolation on i16 samples

The following code

pub fn sinc<S: Signal<Frame = [i16; 1]>>(
    source: S,
    source_rate: f64,
    target_rate: f64,
) -> impl Signal<Frame = [i16; 1]> {
    let ring_buffer = ring_buffer::Fixed::from([[0]; 100]);
    let sinc = Sinc::new(ring_buffer);
    source.from_hz_to_hz(sinc, source_rate, target_rate)
}

yields

When the problem occurred, I tried downsampling from 44,1kHz to 16kHz.

Possibly related to #73 and #167.
