Loading Excel table into Detailed Tab of Entity and Attribute section

[lh-usgs]

Describe the bug
Version 2.0.7 of the Metadata Wizard will not open an Excel file (xlsx) table. Saving the file to an older version of Excel (extension xls) does work. However, version 2.0.6 will open an xlsx file, so it's surprising that 2.0.7 cannot.

To Reproduce
Steps to reproduce the behavior:

1. Go to Entity and Attribute Section (Metadata Wizard version 2.0.7)
2. Click on 'Browse to Dataset' on one of the Detailed tabs
3. Choose an xlsx file from your machine to load into the Wizard
4. An error is given saying it could not extract the data from the file, and that Excel xlsx file is not supported.

Expected behavior
All the column labels from the Excel file should get loaded into the Wizard (as well as the enumerated categories), so the metadata descriptors can be added
