DEP: Bump Cython to 0.29.13
In preperation for Python 3.8, we need to ensure we compile the sdist
with new enough versions of Cython. This is the latest current release.

xref https://github.com/pandas-dev/pandas/issues/28341
Just the SSL doc build issue causing the failure. LGTM.  is the SSL thing something we can suppress for a day? By "suppress" do you mean ignore, or a configuration change?

I'm happy to just ignore for a day or two to see if things resolve
themselves.

 thanks @TomAugspurger  Owee, I'm MrMeeseeks, Look at me.

There seem to be a conflict, please backport manually. Here are approximate instructions:

1. Checkout backport branch and update it.

```
$ git checkout 0.25.x
$ git pull
```

2. Cherry pick the first parent branch of the this PR on top of the older branch:
```
$ git cherry-pick -m1 b3bd4dfc855732c81de1019090fe4bc9b7354788
```

3. You will likely have some merge/cherry-pick conflict here, fix them and commit:

```
$ git commit -am 'Backport PR #28391: DEP: Bump Cython to 0.29.13'
```

4. Push to a named branch :

```
git push YOURFORK 0.25.x:auto-backport-of-pr-28391-on-0.25.x
```

5. Create a PR against branch 0.25.x, I would have named this PR:

> "Backport PR #28391 on branch 0.25.x"

And apply the correct labels and milestones.

Congratulation you did some good work ! Hopefully your backport PR will be tested by the continuous integration and merged soon!

If these instruction are inaccurate, feel free to [suggest an improvement](https://github.com/MeeseeksBox/MeeseeksDev).
                 I'll do the backport.
