Reserved Chainlink Crate

Due to the wild-west nature of crates.io, we can't own a "chainlink" namespace that we fully control. This means that certain crate names that we have a high likelihood of using in the future could be claimed by malicious actors.

These crates have no functionality yet, they are just so we can stake our claim to the "high value" Chainlink crate names.

I'll go on the record and say that I really think crates.io should support namespacing. This is a real problem and the solution used here is incomplete, toilsome, and dirty.
