Subject: [PATCH 1/2] Add taskmd checklists for pandas object types

Adds markdown files with checklists of methods and properties for
pandas object types in scope for leanframe (DataFrame, DataFrameGroupBy,
SeriesGroupBy, Rolling, Expanding, ExponentialMovingWindow, Resampler).
The files follow the taskmd format.
