Integrate with metalsmith-collections about default-values

[woodyrew]

Interesting, I use it early in my build chain to add defaults where they're not set but this is an equally sensible workflow.

On a side note, this would work with collections I believe:

.use(defaultvals([
  {
    pattern: ['posts/*.md', '!posts/index.md'],
    defaults: {
      layout: 'post.njk'
      collection: 'posts'
    }
  }
]))
.use(collections({
    posts: {
      sortBy: 'date',
      reverse: true
    }
}))

I'll have a look at adding match to the functionality. Thanks for the suggestion.

Closing since the comment by @woodyrew is a better way to pair collections with default-values
