Temp files created from LOBs not cleaned up until program shutdown #638

@luis100 I also noticed millions of files in /tmp with names such as dbptk15571006134030973464lob

It seems like cleanResources() is not called until DBPTK quits, causing the /tmp directory to grow to 100's of gigabytes during indexing. This is not strictly related to mime detection, would you like a seperate issue for this?

Our workaround was the following cron job while indexing SIARD files with a large number of LOBs:
*/2 * * * * root docker exec <container> find /tmp -name "dbptk*" -type f -mmin +1 -delete

Seems to be caused by this line:

TemporaryPathInputStreamProvider temporaryPathInputStreamProvider = (TemporaryPathInputStreamProvider) binaryCell .getInputStreamProvider();

Where cleanResources() is not called on the TemporaryPathInputStreamProvider until program shutdown.
