Move convolution code to Convolutions.jl submodule

6

Not sure if `xcorr` belongs in there, and currently the `deconv` function calls `filt`, so that can't be moved into convolutions.jl as-is either.

As mentioned in #576, copying here for convenience. It would be nice if any past contributors could shed some light on the algorithm, and even if there's nothing wrong a...

(voodoo) Patch `_small_filt_fir!` performance for 1.12

Benchmarks show that the previous hack for larger values of `19 out = zeros(10_000); julia> @benchmark filt!($out, b, a, x) setup=(x = rand(10_000); b = rand(15); a = 1) ###...

Add FFT convolution kernels

1

This is a draft for adding FFT convolution kernels (that are also plans), which are useful for repeated convolutions. A lot has been adapted from the code [here](https://github.com/JuliaDSP/DSP.jl/issues/358#issuecomment-3013551397), courtesy of...
