Update to crates.io
We did not update crates.io for the 0.11 release of the Rust implementation of Apache Arrow. I believe that the Rust version is on the same release cycle as the other major implementations as we did release for 0.10 with the other implementations.
I don't have permissions to do this, could someone (Andy maybe?) help? Note, this is not urgent but we should keep crates.io updated so that people can see that we are making progress on the Rust implementation.
