We were monkeypatching pd.ExcelFile but used ExcelFile imported directly in tests which was causing this to run exclusive of the specified engine. Figured easiest just to stick with the pd namespace

openpyxl seems to exhaust a pd.ExcelFile after reading whereas xlrd does not. I don't think we really have a preference here and I can't imagine that the xlrd behavior is necessarily required so just created a new pd.ExcelFile after each use

This didn't really follow the same rules for parametrization as the rest of the items in TestExcelFileReadso figured clearest to remove from class

do we normally need to close the file? use in a context manager?

It looks like it depends on what type of object ExcelFile is interacting with but ultimately converted usage to a context manager to be safe

The writer tests still assume xlrd to be there. Will fix up in a follow up to address proper parametrization here (have focused more on readers given recent PRs)
