Research direction
Start at find_file_in_zip() and inspect how candidate_files handles .twb and .tds entries in a .twbx containing custom geocoding. Reproduce with a workbook archive containing both file types if possible. Done means .tds files are not evaluated as workbooks and the .twbx opens without TableauInvalidFileException.

Description
Hello,
I was trying to open a 9.3 workbook with custom geocoding attached. find_file_in_zip() evaluates .tds files as well as .twb files when opening a .twbx. A .twbx can contain .tds files if it contains custom geocoding.
I'm not quite sure what determines the order of the filenames in candidate_files, but if a .tds happens to end up before a .tdw in the list, the .tds will be evaluated first as a workbook. This raises the TableauInvalidFileException: filename is not a valid 'workbook' file.
I cannot share the workbook (it contains private data), I can share some screenshots of its contents:


A suggested fix for this would be to only check for .twb's if the file is a .twb/.twbx.
Cheers,
Marco
