thanks for also taking care of Rust!

test_value,
cmplx!(gq3_moment(N as usize, NF as f64), 0.),
rel = 4e-4
rel = if NF != 6 { 4e-4 } else { 2e-3 }

both gamma_gq and gq3_moment are coming from Falcioni et al., right? should we tell them that they got worse, i.e. they don't follow their own boundary condition? I know we are talking 1e4 here, so it is stupid - it may still indicate a possible typo ...

eh yes, I saw your email, but it could well be that the typo is from my side!! I'll try to double check the changes nex week.
