ntlm: RDoc is not a full Ruby parser and will fail when fed invalid ruby programs: undefined method `[]' for nil:NilClass

First and foremost, many thanks for this library! 🙇 👍 FYI and in case something can be done about it, I got an error related to ntlm's documentation during installation:

Before reporting this, could you check that the file you're documenting
has proper syntax:

  ${HOME}/.rbenv/versions/2.6.3/bin/ruby -c lib/net/ntlm.rb

RDoc is not a full Ruby parser and will fail when fed invalid ruby programs.

The internal error was:

	(NoMethodError) undefined method `[]' for nil:NilClass

ERROR:  While executing gem ... (NoMethodError)
    undefined method `[]' for nil:NilClass

It didn't seem to prevent from importing the library though:

$ irb
irb(main):001:0> require 'kindle_highlights'
=> true

I'm experiencing this issue as well 👍

There are some issues with the current implementation because Amazon has changed the structure of their login page. I am working on a fix but don't have an ETA.
