PYTHON-1358 Add a TimeUUID class

[SiyaoIsHiding]

Closes PYTHON-1358. Based on Cassandra's implementation and the issue reporter's code.

I am considering where to put the class TimeUUID and the relevant tests. I currently put them in util.py and test_types.py, which is weird. Any suggestions?

Any requests for changes are welcomed.

Signed the cla. And do I need to do anything about the Python 2 thing?

Hey @SiyaoIsHiding , nice to (virtually) see you again! And hey, thanks for the PR! Apologies for the delay in getting back to you; we've been trying to get multiple releases out at the same time and (as usual) we're running behind a bit.

Re: the Python 2 thing... you mean the AppVeyor build + tests, right? Yeah, you can completely ignore those for now. The AppVeyor builds for several of the drivers need to be updated so for now that's a no-op... focus on the Travis builds instead.

It looks like this PR is still in draft... are you at a spot where I should be reviewing anything here? Or do you still have some work you want to do on it?

Hi @absurdfarce , excited to join your team!
No rush on this PR. I was just trying to familiarize myself with the codebase and I understand this issue is a minor priority.

This is still a draft PR because I am considering where to put the class TimeUUID and the relevant tests. I currently put them in util.py and test_types.py, which is kinda weird. Do you have any suggestions?

Again, no rush at all. And looking forward to working with you in the team soon!
