Use non-nullable parameters for operator == (#264)
The null value will never be passed to the equals operator
implementation. Widening the type causes any other class which
implements this interface to also widen the type.

+## 2.1.3
+
+- `operator ==` overrides no longer take nullable arguments. This is only
+ visible for classes that implement the interfaces defined in this package
+ which no longer need to also widen the argument type.

## 2.1.2
- Fix to `Quad.copy` ([#221](https://github.com/google/vector_math.dart/issues/221))
