2.0.0

Major updates

• Switches from open-uri to Net::HTTP. This is a potentially breaking change.

• request_options are now used to configure Net::HTTP.start.

• Rather than using all string keys from request_options, HTTP headers are now
  specified in their own headers hash. To upgrade, any options intended as
  headers need to be extracted into a headers hash, e.g.

    validates :password, not_pwned: {
  -    request_options: { read_timeout: 5, open_timeout: 1, "User-Agent" => "Super fun user agent" }
  +    request_options: { read_timeout: 5, open_timeout: 1, headers: { "User-Agent" => "Super fun user agent" } }
    }
  
  -  password = Pwned::Password.new("password", 'User-Agent' => 'Super fun new user agent')
  +  password = Pwned::Password.new("password", headers: { 'User-Agent' => 'Super fun new user agent' }, read_timeout: 10)

• Adds a CLI to let you check passwords on the command line

  $ pwned password
  Pwned!
  The password has been found in public breaches 3730471 times.
