Try bumping mkl-src again

[emmatyping]

Since it seems the build doesn't work...

[emmatyping]

Ah, seems to be https://github.com/rust-math/intel-mkl-src/issues/68

[emmatyping]

Would it be acceptable to pin anyhow in the Cargo.toml until a new intel-mkl-src release is made?

It might make sense to wait for Toshiki to merge and release. If it is urgent, one could depend directly on intel-mkl-src and constrain anyhow instead of going via blas-src.
