Dicts from parsed datetime with a timezone cannot be deep-copied

[jpsca]

The resulting dict from parsing a datetime with a timezone cannot be deep-copied using
the stdlib function copy.deepcopy().

Example

import copy
import toml

o = toml.loads("dob = 1979-05-27T07:32:00-08:00")
copy.deepcopy(o)

What happens now

TypeError: __init__() missing 1 required positional argument: 'toml_offset'

What should happen

The dict is copied and the timezone of the copy has the same offset but it is a different object.

I'm running into the same issue too.

I see you have a commit in your own fork @jpsca

Yes, and I made a PR with the fix: #309
