New release with binaries on Conda Forge

[saasaa]

Hello and thank you for maintaining this library.

Would it be possible to build and upload new binaries to Conda Forge?
I have a couple of Windows Users who want to use my recent pull request , but unfortunately cannot be bothered to build slycot manually.

Thank you and all the best

Yes, it's long overdue. See #204

I have cut a release for Slycot 0.6. Packages should appear on conda-forge soon.
