Merge #64: Introduce exposed API check

6b70a27 Add the exposed API check to the existing Lint CI (Nick Johnson)
ddf7c06 Initialize the api files (Nick Johnson)

Pull request description:

  I've appreciated this check over in `rust-bitcoin` and think it can help here as well. Initialing the api files in the first commit by running `cargo rbmt api`. Added the check to CI by extending the existing Lint job, I don't think we need to go testing the 20 parallel jobs limit anytime soon since these are all pretty quick. Bet let me know if there is a preferred job breakdown.
