ParallelScatterZipCreator leaks temporary files (and maybe more)

As indicated by https://issues.apache.org/jira/browse/COMPRESS-446?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16679878#comment-16679878 COMPRESS-446 may have closed one resource leak but not all of them.

If an exception occurs in writeTo we may miss calling close on some of the ScatterZipOutputStream}}s which in turn may leak resources like temporary files opened by using {{FileBasedScatterGatherBackingStore.

This affects all versions since 1.10
