ASV: Add xlrd engine for xls file
- [x] Ensure all linting tests pass, see [here](https://pandas.pydata.org/pandas-docs/dev/development/contributing.html#code-standards) for how to run them

Is one parametrized function more efficient than multiple functions during setup and teardown? If not I would make a separate function for the xls benchmark

this is fine, the setup time doesn't make much difference. @phofl thanks for the follow-up!
