Consider adding a way to better interact with streamer reports as objects

(You should have some way to define priority on issues. This is a low priority case)

As of today, I can do something like

```
download_stream 'output 1'
```

which is a good way to inspect the output of a variable, but may also be nice to be able to download a whole stream report. Something like

```
download_streamer 1
```

but this will only be useful if I can then interact with the report. So, maybe it is a good idea to basically build a new streamer tool, similar to the controller, or sensor-graph, so I can do

```
streamer 1
(streamer) download_report
(report) list_streams
1, 2
(report) show 1
Stream 20481: 710 at 2017-04-17 14:06:42.883891
Stream 20481: 710 at 2017-04-17 14:06:42.883891
(report) write_to_file my-report.bin
```

You get the idea. Basically, now that we have *Streamer Reports*, reports themselves should be first class citizens.
