Can't get authors data

[koki-73]

Hello, this gem is so nice to use PA API.
But I couldn't get authors data by using authors method like "item.authors".

I checked this paapi file, and I guess there is room for improvement.

When I request book data (market is jp), the request about authors is like as below

 "ItemInfo"=>
    {"ByLineInfo"=>
      {"Contributors"=>
        [{"Locale"=>"ja_JP", "Name"=>"###", "Role"=>"著", "RoleType"=>"author"},

but item.rb file is like as below

  def contributors_of(kind)
      kind = kind.to_s.gsub(/([[:alpha:]]+)/) { |w| w.capitalize }
      contributors.select { |e| e['Role'] == kind }&.map { |e| e.dig('Name') }&.reject {|n| n.to_s.empty?}
  end

  def authors
      contributors_of 'Author'
  end

so I think you might want to change like as below

  def contributors_of(kind)
      kind = kind.to_s.gsub(/([[:alpha:]]+)/) { |w| w.capitalize }
      contributors.select { |e| e['RoleType'] == kind }&.map { |e| e.dig('Name') }&.reject {|n| n.to_s.empty?}
  end

  def authors
      contributors_of 'author'
  end

I would greatly appreicate if you can give our proposal a good review.

Thanks for the bug report. It seems Amazon has started using RoleType and lower case values. I've updated Paapi to match, as suggested and pushed a new version of the gem.
