X-points are just saddle points in psi (or psi_N). The IMAS DD has a place to enter them with equilibrium data, but our current toolset is not doing that entry because they're not in gEQDSK files and EFIT.jl isn't finding them. Maybe this feature should be in EFIT.jl, but it'll be easier to draft it here for now and offer it to EFIT.jl later.
