[FR] enable calling with orientation angles #6

It is often the case that one needs to call a full amplitude with the plane orientation. Here is an example of such function from Lc2pKpi decay. (the last phase term can be dropped)

amplitude_full(chain, σs, (ϕ, cosθ, χ), two_m, two_λp; refζs=[1,1,1,1]) = sum(
    conj(wignerD_doublearg(1, two_m, two_m′, ϕ, cosθ, χ))* 
    amplitude_aligned_pπK(chain, σs, two_m′, two_λp; refζs) * exp(im *(two_λp)/2* χ)
    for two_m′ in -1:2:1
)
