In this pull request, we have improved the calculation of the comoving distance:

• We have removed QuadGK, using instead Integrals. The integrations algorithm employed is the same, but the latter has rules for AD.
• We have added a faster integration method, based on FastGaussQuadrature.gausslegendre. This is tested against the former, adaptive method.
