Print area cannot be parsed if it's a reference to a Table
Excel allows users to create tables and set the print area as whatever the area of that table is. This results in a definedName tag in workbook.xml that openpyxl cannot parse (expects a cell reference)
See attached file, which produces something like
```
<definedNames>
<definedName name="_xlnm.Print_Area" localSheetId="0">InvoiceData[#All]</definedName>
</definedNames>
```
This crashes out in the workbook reader as it attempts to extract a cell reference ([See here](https://foss.heptapod.net/openpyxl/openpyxl/-/blob/branch/3.1/openpyxl/reader/workbook.py#L117))
The spec (at least according to [c-rex](https://c-rex.net/projects/samples/ooxml/e1/Part4/OOXML_P4_DOCX_definedName_topic_ID0E2JB4.html)) doesn't really provide much guidance on this one. I'm unable to test how LibreOffice handles it.
openpyxl 3.1.0b1
Sample Code
```
from openpyxl import load_workbook
wb = load_workbook("QueryTable.xlsx")
