Importing Excel Sheets
The option `HEADERS` has three possible values:  
* `FORCE`: treat the first row as a header
* `DISABLE` treat the first row as a row of data
* `AUTO` attempt auto-detection (default)  
For example, to treat the first row as a header, run:  
```sql
SELECT *
FROM st_read(
'test_excel.xlsx',
layer = 'Sheet1',
open_options = ['HEADERS=FORCE']
);
```
