No becauseof the call to `list()` that cannot be const.

I missed the feature of trashSpaceInfo, thank you for pointing it out.

We need to add the UDS_SIZE field here : this is a missing feature for a special common use case : Finding out what amount of space is occupied by the trashed files ?
The trash size should be easy to find out for users. Plus we have a cache file to get this information cheaply.

UDS_SIZE may not be used that way currently but it is semantically correct nonetheless.
In most other cases directory size calculation is not used because it is too resource intensive but here we have the value pre-computed.

And by the way the trash:/ has not `Properties` entry in its context menu, so it is not even possible to get the trash size currently.
