Display VATSIM ATC extended sectors

[Heclak]

In VATSIM, it is common practice for ATC to extend themselves to control multiple sectors at the centre level. Currently, Elevatex only shows the primary sector and doesn't display any information of extended sectors. It would be more accurate to allow interpret and display the extended sectors. You can reference the CTR controllers at Australia and NZ who are very commonly controlling more than one sector at a time.

Presently where we get the data from does not provide this, it is on their to-do list so once they support it we can as well.
