macOS maintenance

[termoshtt]

Current MKL update procedure is following:

1. Update system MKL using package manager (pacman on ArchLinux, or manually on Windows)
2. Create packages (mkl-*.tar.zst) using intel-mkl-tool
3. Upload them onto AWS S3 ( this may be merged into 2. Upload to S3 using rusoto #41 )
4. Update hard coded version of MKL

However, I have no macOS machine, and procedure 1 is hard for me.

@termoshtt I've created macOs packages with step 1. There are 8 package, each about 170MB. How can we get these uploaded to s3?

This would be super nice to have working. @termoshtt any chance @pmarks could upload to s3?
