LanczosResampler's hard-coded buffer sizes can get into trouble.

[sdatkinson]

A DAW buffer size of 4096 will get into trouble trying to use these when resampling.
Here's the offender:

AudioDSPTools/dsp/ResamplingContainer/Dependencies/LanczosResampler.h

Line 135 in b62f49c

static constexpr size_t kBufferSize = 4096;

Short-term fix: bump it up for the most extreme case I can foresee (44.1 -> 192k with buffer size 8192). Longer-term, fix the code.
