SA1000: Spacing around new() expression inconsistent with formatter support

[tillig]

In C# 9.0, you can omit the type name when using new in some cases:

// With the type name
List<int> ws = new List<int>();

// Without the type name
List<int> xs = new();
List<int> ys = new(capacity: 10_000);
List<int> zs = new() { Capacity = 20_000 };

The SA1000 rule catches new() and wants a space like new () because it assumes the next thing should be a type name. It should treat new() like a function instead of like new TypeHere() with respect to spacing. That would also allow C# formatters, which treat new() like a function, to be consistent with StyleCop rules. (Right now they fight a bit.)

It looks like there's already a unit test around this so perhaps this just hasn't been released yet?

I'm dumb and need to RTFM. Updated to 1.2.0-beta.321 and all is well. Sorry for any confusion.
