Explicitly set Hex package files

Closes #265

Sanity check:

% mix hex.build --unpack -o pkg
% iex

This also might be a good idea:

I'll take it from the horse's mouth that this is the right way to do it! Thanks @wojtekmach ; I'll be copying this into my other projects as well.

[mtrudel]

Oh wait - what about the stuff in assets/; that'll be required to build docs locally, no?

[wojtekmach]

assets aren’t used in Hex package. They are present in your local checkout when you run mix docs so it’s all good. :)

[wojtekmach]

Ah, you can keep the defaults but exclude what you don't need:

exclude_patterns: ~w[priv]

lmk if you want me to send a PR!

[mtrudel]

Do I need to?

[wojtekmach]

Nope, it's fine as is. Just letting you know there's another way, created basically for this scenario, to solve the problem. :)

[mtrudel]

Got it. I'm going to be passing over my other projects and applying this as needed, so it's great to know.

Thanks!
