Patching fix for Tika-521 on Tika 0.8

[Jana, Kumar Raja]

Hi,
Is it possible to patch the fix for Tika-521 to Tika 0.8 without upgrading to 
POI 3.8?

There is TikaExcelEventBasedExtraction.diff attached to the Jira case, can this 
be used to resolve the issue? We are tied down to POI 3.7 and cannot move to 
POI 3.8 due to compatibility issues with other code.

Thank you.

Regards,
Kumar
