Incorrect use of extended sectors

[Adrian2k]

There are areas where sectors are defined twice instead of once in areas where a sector covers above another.
The use of two sectors like this is only supposed to be used for FIRs crossing the W180 longitude.

Affects the following FIR's:

• CZQM
• CZQX
• ESOS
• GMMM
• LECM
• LIMM
• SKED
• VVHM
• WBFC

I'll try to get to it when I can, but the gist of it:
Extend main VVHM area to cover the "extended section", this will mean VVHM and VVHN will overlap in that area.
Same for WBFC, except WBFC will completely overlap WBGG.

ESOS no longer incorrect! ✅
