Somehow cleanup any reources that are created during tests even on failure

[sckott]

I know this happens as i'm developing sixtyfour. That is, although examples and tests I think all cleanup resources after themselves, if there's a failure before the cleanup step the resource doesn't get cleaned up.

Probably via https://testthat.r-lib.org/articles/test-fixtures.html somehow we can do this for tests at least. I'm not sure there's any way to do for examples

Right now, simply checking manually from time to time in the AWS console if there's any resources to cleanup
