Mark a boundary condition as being used as an internal Cartoon boundary.
The cartoon method requires a ZernikeB1 basis to be stable at small \(x\), which should not have a boundary condition applied. However, FD does require ghost zones to be filled on this boundary, so is_cartoon() can be used to determine whether to treat this boundary condition as something to implement or skip.
