Vector3 rewrite

[oliverbooth]

Rewrite closely resembles .NET Vector3 struct, adding many helper methods and useful default values.

The Vector3 code from .NET has an MIT license, it most likely requires attribution if this is to be included.

To be honest I think general vector math functions are outside the scope of VpNet as a library, and that it should be more minimal. If someone needs to use these features they can always use the original Vector3 struct.

I'd be more in favor of having types that say something about the purpose of the data, for example a Position or Rotation type. As it is Vector3 already does not even work for object rotations because it requires 4 floats. There's actually also no reason for everything to be a double, since the only thing in VP SDK that is actually sent across the wire as a double is an object position.

In that case, perhaps it would be better to simply reference System.Numerics.Vectors nuget and use that?
