Instead of looking for presence of `word/document.xml` ,
`ppt/presentation.xml` and `xl/workbook.xml` to identify DOCX,PPTX and
XLSX files, we look for prefix `word/document*.xml`,
`ppt/presentation*.xml` and `xl/workbook*.xml` as certain files
generated from office365 has files with different names.

**Summary**
Relax table-segregation rule applied during chunking such that a `Table`
and `Text`-subtype elements can be combined into a single chunk when the
chunking window allows.
**Additional Context**
Until now, `Table` elements have always been segregated during chunking,
i.e. a chunk that contained a table would never contain any other
element. In certain scenarios, especially when a large chunking window
of say 2000 characters is used, this behavior can reduce retrieval
effectiveness by isolating the table from surrounding context.
