Hi!

I've been using tqdm lately along with the set_postfix function. I noticed that in the documentation it says that you can provide not only a dict but also an OrderedDict. The OrderedDict works as expected, but the option postfix in the tqdm class does not work as expected if you provide an OrderedDict (i.e., the order is different from execution to execution, I guess that due to the PYTHONHASHSEED envvar or similar which helps to initialize the dictionaries order). In the documentation we can see that postfix: dict or *, optional, so the documentation is correct (i.e., it doesn't mention OrderedDict). But since for the set_postfix we can see that in the documentation allows dict or OrderedDict, I think that it makes sense that the postfix option of the tqdm class would also accept an OrderedDict to preserve the order of the parameters. I guess that the change shouldn't be too difficult since currently when postfix is provided in the tqdm class, it "calls set_postfix(**postfix)".

Thank you!
