Interpolator for resampling a stream of floats using Catmull-Rom interpolation.
Note that the resampler is stateful, so when there's a break in the continuity
of the input stream you're feeding it, you should call reset() before feeding
it any new data. And like with any other stateful filter, if you're resampling
multiple channels, make sure each one uses its own CatmullRomInterpolator
object.
