STYLE keep local imports relative

• Ensure all linting tests pass, see here for how to run them

xref this comment:

more generally, i like relative imports for same-directory as it clarified dependency structure

+1, I also find this helpful. I think it should certainly be doable to have a check that relative imports are never outside the local directory

@jorisvandenbossche @jbrockmendel is this what you had in mind?

Like this, imports in the same folder are relative, and those outside are absolute.

So, for example, in pandas/_testing/_io.py:

• from pandas.io.common import urlopen stays absolute
• from pandas._testing.contexts import ensure_clean becomes from .contexts import ensure_clean

-1 on this
let's leave imports alone for now
