RKDA and RKDA-E define excessive center coordinates for FIR boundary

[dneuge]

Generated FIRBoundaries.dat contain the following lines:

RKDA|0|0|67|32.5|124|38.6361|133.647211|105.143991|128.290184

RKDA-E|0|0|22|35.411667|127.560833|38.6361|133.647211|120.689693|128.530449

The second-last value is supposed to be the latitude of the FIR's center point according to documentation. If liberally interpreted 105.14°N and 120.69°N cross the poles (latitudes should not exceed ±90°) which would make those points wrap to the other side of the earth, moving the center coordinate from the original boundary box between South Korea and Japan to in between Greenland and Canada (somewhere around 60°N 52°W).

The error appears to be taken over from label_lat fields in Boundaries.geojson.
