Cannot read xlsx files with non standard internal sheet.xml names
Created originally on Bitbucket by max22 (Max Böhm)
openpyxl cannot read worksheets when the internal xml data files do not follow the naming convention sheet1.xml, sheet2.xml, ...
The [Content_Types].xml file contains the list of actually used xml data sheetnames. The sheetnames should be taken from here.
A patch of reader/excel.py is attached (based on the 1.8.3 version).
