Optional w3 upon package instantiation became unwieldy - a la discussion in #67

Instead of making a w3 instance optional upon Package instantiation, require it whenever creating a Package object

I left Package.set_default_w3 so that you can change the default w3 instance - which seems like something we want? (ie. to switch chains to fetch a certain deployment??)

Closing since #80 was merged (since it was approved) that contained these changes
