feature: multiple-values and separator

[YusukeHosonuma]

Support multiple-values to output like print of standard library.

Example

print("Hello", 42)
// => "Hello" 42

Debug.print("Hello", 42)
// =>  "Hello" 42

Debug.print("Hello", 42, separator: ", ") // use custom `separator`
// =>  "Hello", 42

Debug.prettyPrint(["Hello", "World"], 42)
// =>
// [
//     "Hello",
//     "World"
// ]
// 42

Limitation

Operator based API such as Debug.p >>> is not supported multiple values. Because operator must have one or two arguments, this is limitation of Swift.

s/target/targets/g

This default value " " is similar to standard library.

[YusukeHosonuma]

Can't use targets: Any... because targets are passed to one array of argument instead of multiple values called from print() in this source.

That is due to Swift language design😎
