Missing call sites

[wheeheee]

I see that it's not really a new issue but the others are closed.
An example on FFTA.jl's main branch:

julia> using FFTA, Cthulhu

julia> x = ones(ComplexF64, 412);

julia> p = plan_fft(x);

julia> @descend p * x  # then after hitting [T] [h] [o]
fft!(out::AbstractVector{T}, in::AbstractVector{T}, start_out::Int64, start_in::Int64, d::FFTA.Direction, t::FFTA.FFTEnum, g::FFTA.CallGraph{T}, idx::Int64) where T @ FFTA Q:\FFTA.jl\src\algos.jl:7
   ∘ ── %0 = invoke fft!(::Vector{ComplexF64},::Vector{ComplexF64},::Int64,::Int64,::FFTA.Direction,::FFTA.FFTEnum,::FFTA.CallGraph{ComplexF64},::Int64)::…

If you un[h]ide then you'll see there's a missing call to FFTA.fft_composite! (which is type-stable).
