Ability to clear individual tasks

Atm it is only possible to clear all tasks at once.

I need enqueue a number of uploads and need to keep track of them to trigger additional tasks once all uploads belonging to a batch are completed. To this end, I persist the taskId in my local database and check each event in the result listener if there
is an entry for this taskId. If there is not, I ignore the event.

Now, it would be nice to be able to remove that particular task from the uploader completely so that it does not keep firing.

For now I only have the option of clearing all tasks which is probably not what I want.
