This enables parsing a json-structure in a streaming way. It allows to pick the values wanted from the original structure via `JsonPath`, a notation to refer to a specific part of a json-structure.
It never reads the original value in memory entirely (unless that is required by the given json-path), but instead parses the incoming values in chunks. This is especially helpful when consuming APIs, which put the results you're interested in in some nested structure, which isn't simply streamable.
A common example would be:
```
{
"rows": [...]
}
```
Where the application is only interested in the values contained in `rows`, preferably as they arrive (over a TCP stream for example).

Sorry I didn't get to include the fixups in time 😞. Thanks for finishing up 👍 |

We'll release the Alpakka today - that's why we're pushing this a bit. |

Yup. No problem at all. Thanks for all the work in the original PR! |
