Enable human-readable output from almanack CLI

[d33bs]

Openly, I wondered if the default behavior of the output returned by almanack <repo path> should be a human-readable table instead of data. We could add a --json flag to return what is currently provided. Perhaps this is an additional issue/ PR at a later time?

I think that sounds like a reasonable idea, if you expect people to be using it interactively rather than parsing it. I think it pertains to this PR so it would make sense to include it here, but it's up to you if you'd prefer for it to be reviewed in more detail in a different PR.
