dcsctp: Make Sequence Number API more consistent

* `AddTo` and `Difference` are made into static methods, as one may have
  believed that these modified the current object previously. The
  `Increment` method is kept, as it's obvious that it modifies the
  current object as it doesn't have a return value, and `next_value` is
  kept, as its naming (lower-case, snake) indicates that it's a simple
  accessor.
* Difference will return the absolute difference. This is actually the
  only reasonable choice, as the return value was unsigned and any
  negative value would just wrap.

WebRTC is a free, open software project that provides browsers and mobile applications with Real-Time Communications (RTC) capabilities via simple APIs. The WebRTC components have been optimized to best serve this purpose.

Our mission: To enable rich, high-quality RTC applications to be developed for the browser, mobile platforms, and IoT devices, and allow them all to communicate via a common set of protocols.

The WebRTC initiative is a project supported by Google, Mozilla and Opera, amongst others.

Development
