Joins dictionary 'b' to dictionary a, by matching the values of a to the keys of b.
Items from b with no matching value in a are excluded from the result.
Items from a with no matching key in b are excluded from the result.
Example:
Received via a:
{<br>
"first":"first_id",<br>
"third":"third_id",<br>
"fifth":"fifth_id"<br>
}@0<br>
```<br>
2. Received via `b`:<br>
```json<br>
{<br>
"first_id":1,<br>
"second_id":2,<br>
"third_id":3<br>
}@0<br>
```<br>
3. Sent via `joined`:<br>
```json<br>
{<br>
"first": 1,<br>
"third": 3<br>
}@0<br>
```<br>
