We can now have saving, compression and incoming speed statistics
changing cbf,edf,fits,hdf5,nxs and tiff to manage statistics

internals operation are normally done in place but it's not always
safe with some type of memory.
i.e: You can not memove on a memory map, this cause a crash.

changed cbf,edf,fits,hdf5,tiff and Nxs to manage parallel file write

To control saving concurrency, you have to change the number of writing task
with method get/setMaxConcurrentWritingTask.

This commit contains also a small fix for write statistics:
As we recreate the container when changing saving type, thoses parameters
were not keeped.

We now set event callback in case of error when writing.

For now is only available for INT 32 images.
