[MERGED PR] Nadir increase to max players allowed (60 > 70)

Isn't Nadir cramped as heck

It feels much more cramped than it actually is (which is intentional to an extent). It's now larger than Oshan in peak dimensional terms on both the X and Y axis; it has trimmed corners compared to Oshan and no research outpost, but also no hole in the center.

Anecdotally, while it's hard not to run into people, it's also still very possible in my experience to find parts of the map where nobody is going to run into you, even during Classic hustle and bustle.
