Hosting MKL binary on GitHub release instead of S3

[termoshtt]

Related #55 #42

Since Intel MKL is licensed by ISSL which allows redistribution, I redistribute them on AWS S3 for download feature. This S3 bucket can be readable from anyone, but writable only by me (@termoshtt). This prevents other developers from maintaining this crate. AWS S3 allows to give writable authority to other developers through IAM, but I do not want to manage them.

I am planning to create a group for managing this repository on GitHub, and hope to sync its authority for MKL binary re-distribution. After some survey for GitHub package and release, GitHub package looks incompatible for this use, and GitHub release assert looks a good option. For example llvm-project distributes ~300MB files in its release page.

If you want to join the new team https://github.com/orgs/rust-math/teams/intel-mkl-src-maintainers , please let me know.
