If you want to block when reading or writing, you must enable it:

```go
	rb := ringbuffer.New(1024).SetBlocking(true)
```

Enabling blocking will cause the ring buffer to behave like a buffered [io.Pipe](https://pkg.go.dev/io#Pipe).

Regular Reads will block until data is available, but not wait for a full buffer.

        `DatasetBase::MakeIteratorInternal()`.
    *   (C++) `IteratorBase::Initialize()` method was added to support raising
        errors during iterator construction.
*   Eager Execution:
    *   Added the ability to pause recording operations for gradient computation
        via `tf.GradientTape.stop_recording`.
    *   Updated documentation, introductory notebooks.
