Update Earth Radius in Release Scripts

[zacadelman]

The earth radius needs to be updated in all release scripts to:

OUTPUT_FILE_ELLIPSOID,"+a=6370000.0,+b=6370000.0”

The vector scripts have the ellipsoid set to 6370997. This needs to be updated in the new release ASAP.

I saw some libraries still use 6370997, do you think our change will cause any conflicts?
