Refine stubs for Python 2's decimal module
Browse files Browse the repository at this point in the history 
The decimal module for Python 2 was relatively incomplete, unlike the
decimal module for Python 3. This commit copies the relevant type
signatures from Python 3's decimal module to Python 2's.

There was a lot of code in both stubs and it wasn't clear to me if it
was safe to merge the two modules together, so I refrained from doing
so.
