return value : true when the dereferenced value is map-shaped

:content
Returns true when the value's current type is `M`, the map/list container type. It does not require contiguous numeric keys; use `is_list()` for that.

```cpp
if(payload.get_by_path("items").is_array()) { /* has children */ }
```
