Is it possible to use '\t' (tab) for indentation instead of spaces in JSON?

[sarahlydia9868]

2 Spaces Tab:

{
  "foo": {
    "bar": {
      "baz": "str"
    }
  }
}

1 Tab Tab:

{
	"foo":{
		"bar":{
			"baz":"str"
		}
	}
}

I want to use tabs instead of spaces to reduce the JSON file size and for better readability.

It is now, on master. I've added an indent_char property to json_options, you can now set the option to indent by one tab by configuring options as

auto options = json_options{}
    .indent_char('\t')
    .indent_size(1);

and passing them to encode and dump functions.
