Close the Wise script and the multipart file after extraction (#104)

Browse Source 
* Look for the Wise overlay header before opening the file again

ExtractWiseOverlay (and ExtractWise for NE) opened a second stream on
the executable for multi-part Wise installers before checking for a
Wise overlay header at all. For any other executable that stream was
never closed, so the file stayed open until the stream was finalized.
On Windows such a file cannot be deleted, so an extraction folder that
contains it is left behind in TEMP.

* Close the Wise script and the multipart file after extraction

ExtractWiseOverlay (and ExtractWise for NE) never closed WiseScript.bin,
which it opens from the output directory, nor the stream with the
installer and its parts, so these files stayed open until their streams
were finalized.

* Keep the original block that opens the multipart file

Close the multipart stream with a separate using declaration after the
block instead of rewriting it.
