option to specify how big LOB-s will be exported outside from siard

[Laurira]

At the moment if user specifies that LOBs should be exported outside (-eel flag), then ALL the lobs will be exported outside.
Problem is that some LOBs are really small, only couple of bytes but the amount of those files can be millions. So the result will be catastrophic for performance when it comes to the file transfer, (de)compressing or any other action with the final result of files.

Now we suggest that user should be able to specify if file is smaller than X MB then it will not be exported outside from siard file.

It would be nice if this feature will work on already existing siards as well. Maybe it should be another feature request then please separate it. But problem is that we two databases which contain millions of small files. Can you add this feature to DBPTK that when converting siard -> siard then small files <1MB will be put back into the siard.
