* Script to copy athena jdbc jar to our maven repo

Since amazon is still not putting their athena jdbc on to maven, the
easiest thing for us to do is setup a maven-y s3 repo and copy their jar
into it.

This script allows you to run:
`./bin/athena.bb <version> [--deploy]`

For example:
`./bin/athena.bb 2.0.35 --deploy`

Will download the 2.0.35 jar from amazon's release bucket, create and
update the necessary maven repo files, then upload all those files to
our maven repo.

It uses the jar build WITHOUT the AWS SDK.

You must have `bb` (babashka), `aws` (awscli), and `shasum` commands available.
You must have aws credentials available, e.g. through `aws configure`

* Add comment explaining script to script

* Use iterate instead of loop for find-pred
