BUG: Make ExcelFile.parse pass kwds to TextParser
Fixes #4131

test2.xlsx is a single column with the following cells:

```
Test
NA
1
NA
apple
rabbit
```
 this looks ok to merge after #4141

 Oops forgot update to release.rst
 @hayd do you want me to make a new PR for that?
 actually what we could use here is a method in io.parsers that give u back all of the default args (and values)
to avoid explicitly listing them in more than one place

used in io.parsers obviously but also here

note - maybe be a smaller subset that io.parser
