An IONEX slant ionospheric group delay with the status of the value.
delay_m is a group delay in positive meters: it increases the measured
pseudorange. The carrier-phase advance is its negation. status is a
Sidereon.GNSS.Ionosphere.SlantStatus, which names anything the value rests
on beyond the product's stated grid.
