Detailed Description

Fast resampler coefficient table.

Coefficient data needed to perform fast resampling. The numToRead table lists the number of inputs to read per output, while the coeff table lists the coeffients per each output. The tables can be looped for continuous operation because the resampler is periodic with period num (the phase increment is den/num).

If time-aligned is false then there will be num entries in numToReadTab. If true there will be num+1 entries, since the first entry will typically push span samples into the convolver fifo, but this only happens for the first output, hence we loop to index 1.
