Problem
Fixes #1283.
Default values for options that are not either string or boolean display as JSON encoded string.
An example would be using IPv4 from ip-num package produces the following as the default value:
(default: {"bitSize":32,"maximumBitSize":"4294967295","type":1,"octets":[{"value":1},{"value":1},{"value":1},{"value":1}],"separator":".","value":"16843009"})
This value is not helpful or user friendly.

Solution
Allow for default values that are objects to utilize a custom toString method to display for the help. The default Object.toString method will not be used. All other types of default values will continue to use JSON.stringify.
NOTE: This did require a signature change of TypeScript typings to communicate that allows for defaultValues to be any instead of just string | boolean.
