Added an overview with categories and a short description of what's inside each file. A link to this overview will be added to the docs, too.
Improved async insert examples; previously, there was a very simple example with a vague name insert_cloud; now, it comes in two variations - with or without the wait_for_async_insert setting. Each variation is more extensive in detail.
Removed "endless" stream examples as this, in my opinion, should be done with async inserts instead. async_insert_without_waiting targets the same use case as it was in the "endless" JSON stream example.
