Detailed Description

Adds or subtracts the singular field to/from the received data on element boundaries.

In the regularized region we solve for the regularized field

\begin{equation} \Psi_m^R = \Psi_m - \Psi_m^P \text{,} \end{equation}

so we subtract the singular field on the regularized side (where field_is_regularized is true) and add it on the other side of the boundary (where field_is_regularized is false). We do the same for the received normal dot flux \(n_i F^i\), but with an extra minus sign because this quantity is defined with the face normal from the perspective of the sending element (see elliptic::protocols::FirstOrderSystem).
