Add an abort() method in focusstack class ?

[jcbenoit]

Hi,
Do you think it is possible/useful, to add an abort() method in the streaming interface of focustack class ?
I think it can be usefull, in cases where wait_done() method returns an error during a processing, in order to abort any scheduled tasks left in queue.

I think the currently existing .reset() method should do it.
