Added tilesearch code, for finding effective parameters.

This is useful code to be able to run.

Also, @DilumAluthge, it contains an example of calling Octavian.matmul_pack_A_and_B! directly. Might be worth copying the function matmul_pack_ab! into the test suit:

function matmul_pack_ab!(C, A, B, ::Val{W₁}, ::Val{W₂}, ::Val{R₁}, ::Val{R₂}) where {W₁, W₂, R₁, R₂}
    M, N = size(C); K = size(B,1)
    zc, za, zb = Octavian.zstridedpointer.((C,A,B))
    nspawn = min(Threads.nthreads(), VectorizationBase.NUM_CORES)
    @elapsed(
        Octavian.matmul_pack_A_and_B!(
            zc, za, zb, StaticInt{1}(), StaticInt{0}(), M, K, N, nspawn,
            StaticFloat{W₁}(), StaticFloat{W₂}(), StaticFloat{R₁}(), StaticFloat{R₂}()
        )
    )
end
