Rename blacklist

[ericdill]

Language matters. https://twitter.com/leahculver/status/1269109776983547904 https://twitter.com/alessandramakes/status/1269116696834437121

I'd also be in ok with any of these *-list prefixes:

• go / green / nice / safe
• stop / red / naughty

This introduces a rename of blacklist -> denylist and whitelist -> allowlist. Backwards compatibility is enabled until such a time as we want to get rid of the backwards compat layer. In the warning message it says "until the next minor release", but that's sort of up to you all since you own the fork now.

As a frequent user of this package I strongly support this idea.

What about using the more common terms include and exclude?

[ericdill]

@xhochy i'd be fine with those too

[analog-cbarber]

The code has changed enough that this pull request should be closed and do this over. I am definitely in favor of just using include and exclude. I think we should also support dependencies using the same format as in conda environment files.
