add wheel to pypi

[samuelcolvin]

Misaka is only available via a .tar.gz file from pypi, currently misaka-2.1.1.tar.gz.

It would improve installation time and portability if you could also distribute a wheel file.

The simplest way to do this with a binary package like misaka is using cibuildwheel this is most easily achieved by performing the build and upload on CI.

Let me know if you need any advice on the best way to set this up.

@samuelcolvin Thanks for the suggestion. I'll take a look at it, but I don't know when I can.

@FSX this would be really helpful. Would you like my help implementing this?
