The conformal spatial christoffel symbols of the second kind.
We define:
\begin{align} \tilde{\Gamma}^k_{ij} &= \tilde{\gamma}^{kl} (D_{ijl} + D_{jil} - D_{lij}) \end{align}
where \(\tilde{\gamma}^{ij}\) and \(D_{ijk}\) are the inverse conformal spatial metric and the CCZ4 auxiliary variable defined by Ccz4::Tags::InverseConformalMetric and Ccz4::Tags::FieldD, respectively.
