Instead of calling a method to find the length of a list, you can use a property (which is a getter under the hood, doing the same thing as `.len()`). This is cleaner and more intuitive, aligning itself more with arrays. Subclassing is now facilitated by a new method, `.chain`. It creates a new list instance by calling the constructor property, instead of statically creating a new ClientList instance. This allows you to create subclasses that inherit from ClientList, without losing that inheritance when calling `.filter` or `.pluck` (methods which create new list instances). The client bundle is now exported lazily, so when you import panic, there's a `client` getter which memoizes a fs call for the client code. This allows compatibility on pre-3.0 versions of npm, where other packages might not be able to recursively find `panic-client`. Also, since it's a getter, it doesn't do the file system call until it's needed.
