Refactor IIR crossover process loop, disable FIR
...
The FIR crossover will need to use FFT convolution, so it can't use the
same loop. Because of that we'll need to rework the FIR crossover to not
use channel SIMD and to work on channel slices instead.

Mark the linear-phase LR24 crossover experimental
...
The low frequency performance is too poor at this filter size and the
DSP load impact is too high. This needs to be implemented using FFT
convolution instead.
