Remove old, non-working examples and low quality demos.

Description of the change

The tvOS, watchOS and macOS Demos have been removed. The new Demo works on macOS and tvOS and there's nothing special that has to be done for watchOS.

None of the examples in Examples work, they're outdated and unmaintained and they don't really offer much help, nor do anything especially informative, so these have been removed also.

They were all laid out in a disorganized way and I've deemed they confuse more than they help. We want to make things as simple as possible for clients to get started with the Rollbar Apple SDK 3.0.0, and to make things as simple as they can be for our Customer Engineers and help desk.

We'll extend the current Demo and add specific examples as needed.
