Adding an asyncio.gather() replacement for tqdm

[SpangleLabs]

tqdm's as_completed() is helpful, but does mean results are not in the same order as inputs, which can be frustrating.

I've tried writing a wrapper which emulates the behaviour of asyncio.gather, though I'm not sure whether this conforms to the ideas of the project. (I'm not sure the typing import will be well appreciated, at the very least)

I'm not too sure how to make this work for older python versions, or whether it's possible, sorry! If someone could point me in the right direction, I might be able to make whatever changes are required

thanks for this. Made a few changes:

• require py3.6+ so await works in list comprehensions
• update test
  • actually verify order of gather() results
  • speed up (no need to sleep())
• tidy syntax
  • e.g. use enumerate()
  • remove typing (would be fine with this in a stub file, tqdm/asyncio.pyi if you want in a separate PR)

Oh that's amazing! I didn't expect that you would fix it all up and neaten it yourself, thank you!
