Description

In some OLE2 containers with embedded objects, we're calling extract macros potentially several times on the same POIFSFileSystem.

An example file is here: https://corpora.tika.apache.org/base/docs/govdocs1/527/527356.doc

The embedded _1152432709.xls has several attachments, including MBD000000B4.unknown and MBD0049C388.unknown among others. Each time we parse the embedded files, we're calling extractMacros on the same file system: root.getFileSystem(), which takes us back to _1152432709.xls.
