Add --functions option to `radon hal`

This allows `radon hal` to examine specific functions as well as files
in general. It required the following refactoring:

- The `Halstead` namedtuple is now `HalsteadReport`. It holds the same
  things.

- There is now a `Halstead` namedtuple that holds a `total` field and a
  `functions` field. `total` is a `HalsteadReport` for the entire
  scanned file, whicl `functions` is a list of `HalsteadReport`s for
  each toplevel function in the file.

- Nested functions are not tracked, only toplevel functions.
