Update ORBX NZ mesh

[Q400]

As the title says update from ORBX for their NZ mesh fixed most problems
introduced by Asobo. A few more fixes still to come but I shouldn't think
that that will be too far away. Queenstown, Milford, Mount Cook seem fine
but I have yet to check the whole country. Just remember there will be more to
come so cut them some slack.

Thanks for the update, I'll re-install it and see how it looks on mine (using XBox series S).
