State: closed

Some more low hanging fruit in the Python 2 removal process.  This should remove all references to the following functions in `pandas.compat` which are redundantly defined for Python 3:
  - `filter`
  - `map`
  - `range`
  - `zip`
  - `next`
  - `FileNotFoundError`
  - `ResourceWarning`
