Bijector constructed from callables implementing forward, inverse, and inverse_log_det_jacobian.

Example Use:

```python
exp = Inline(
  forward_fn=tf.exp,
  inverse_fn=tf.log,
  inverse_log_det_jacobian_fn=(
    lambda y: -tf.reduce_sum(tf.log(y), reduction_indices=-1)),
  name="exp")
```

The above example is equivalent to the `Bijector` `Exp(event_ndims=1)`.
