Slow memory allocation and fragmentation occurs in `getInterpolatedData()`

getInterpolatedData() allocates its output array one index at a time, resulting in fragmentation and slow performance. This can be fixed by pre-allocating the output array. I did this in PR #11

For more evidence of how much faster pre-declaring the array size is, please see:
