add nested package declaration

Fixes Issue #26 with a poorman's version of indent prettier

Seems good, thank you!

I don't like that we have indentation / formatting code strewn around, and I was thinking about maybe using Prism to "prettify" the output Ruby. Then we don't need to care so much about indentation. WDYT?

Open to it, but I'd rather not depend on external gems if we can avoid it?

Ya, I'd also prefer not to depend on external gems, but the generated code won't depend on anything. For now I think we should just treat indentation as "best effort". IOW lets fix what we can, but not worry about it if it gets too hard.

Another option is that folks could make code formatting part of their compilation process. I'm imagining something like:

$ bin/protoboeuf --stdout path/to/some/protoc_file.protoc | prettify > output.rb

Sure that seems fine. We could also include a prettify.rb script which depends on prism.
