Adds sbt-typelevel

[tlazaro]

Added sbt-typelevel, mostly following the instructions on the site, trying to stick to the defaults and typelevel/paiges#449.

• Set the license to Apache
• JVM only for now
• Scala 2.13 only but prepared the build to support multiple versions, just add to crossScalaVersions at the top
• Adds NoPublishPlugin to all modules so there is no publishing yet
• Adds doc project but kept empty

@johnynek if you could take a look and let me know what to do about these AWS failures. Maybe just ignoring these tests for now?

Also, should we be working on this branch or master?

[johnynek]

oh weird... somehow this branch got set as the default. We should change that.

So you can comment out the test, but the bigger question is why are we hitting any AWS initialization code? There is probably something impure going on that is breaking things that will bite us elsewhere.

It may be as easy as finding something and making the initialization lazy val but the "correct" approach would be to use IO better.

Lastly, cats-effect got much better in cats-effect 3 (fixing the need for Blocker to be passed around everywhere, but it isn't available for 2.11, so if we were to use this in a 2.11 repo, it is something to think of).

[johnynek]

but to be clear: just comment out anything you need to get this green, then we will deal with the better fix later.

[johnynek]

I've set the default branch to master, but let's keep this pr against this weird one, and then just force push the weird one to master.

[tlazaro]

Perfect, will pick this up later today.

I would like this repo to work with 2.11 so we can use this at work without trouble but we would have to leave so much behind... What a pain :/

[tlazaro]

Ah BTW, what license should be used? I set it to Apache to try it out.

[tlazaro]

Basically in S3App we just need to make these lazy:

lazy val s3Client = s3.AmazonS3ClientBuilder.defaultClient()
lazy val awsIO = new AWSIO(s3Client)

Not sure what Mergify is about, let me know what else needs to be done in this PR.

[johnynek]

looks good, but big diff...

[johnynek]

mergify can automatically merge some changes (e.g. those from scala-steward that are green).
