Pandas read_excel: only read first few lines
#### Code Sample, a copy-pastable example if possible

```python
workbook_dataframe = pd.read_excel(workbook_filename, nrows = 10)
```
#### Problem description

Using pandas read_excel on about 100 excel files - some are large - I want to read the first few lines of each (header and first few rows of data).

The above doesn't work but illustrates the goal (example reading 10 data rows).
