Default folder structure should be compatible with .gitignore

[cstby]

Problem

I'm using this CLI to put my compendiums under version control. Currently, this module packs and unpacks compendiums to /packs/compendium/_source. Afaik, it's not possible to create a .gitignore file that includes only the nested _source subdirectories and excludes the rest of the files.

Suggested Solution

The DND5e system solves this problem by using a different folder structure: /packs/_source/compendium. This allows them to easily version control the desired files by adding the following lines to .gitignore:

packs/*
!packs/_source/
