The compression filter driver is introduced as suggested by Max.
A sample usage of the filter can be found in the test #214.
Now, multiple clusters can be written compressed.
It is useful for the backup job.
v8: The filter child was changed from the 'backing' to the 'file' one.
Discussed in the email thread with the message ID
