Failing to write following example with `write': undefined method `root_object'

[c0diq]

Just followed the instructions from the README to the letter and getting error

/vendor/bundle --global/gems/nanaimo-0.2.6/lib/nanaimo/writer.rb:48:in `write': undefined method `root_object' for #<Hash:0x00007ff08b0d0308> (NoMethodError)

changing it to would probably fix it -- if so, please send a PR updating the README?

ascii_plist_string = Nanaimo::Writer.new(Nanaimo::Hash.new(project_hash)).write
