Make `TypeSafeStream` extend `Stream`.
This makes it automatically compatible with future additions to `Stream`,
like the `groupBy` method which will be added in SDK version 1.24.
It inherits the default implementation, which will use the `listen` method
of the `TypeSafeStream`, returning a `TypeSafeStreamSubscription`, and will
just have a type check for each event before the listener even sees it.

+## 1.13.3
+
+* Make `TypeSafeStream` extend `Stream` instead of implementing it.
+ This ensures that new methods on `Stream` are automatically picked up,
+ they will go through the `listen` method which type-checks every event.
+* Enable Travis integration.
+* Format with dartfmt.
+* Remove some unused imports.
+
## 1.13.2
* Fix a type-warning.
