Preserve escaped quote characters in argument values

[mikemybytes]

As for now, quote characters are being removed from the argument values using replace(...) call. Yet, in certain use cases, they may appear inside. Typically, when a special character should not be treated as one, some kind of escaping is required (like prefixing it with \). A similar solution could be considered here.

There's a similar quoting-related issue with using braces (curly brackets) with default indexed argument placeholders syntax. There, instead of introducing rather tricky quoting logic, an alternative syntax (positional arguments, see #25) has been introduced.

A similar approach could be adopted here. Since there's a way to use a different quoteCharacter, implementing escaping logic feels unnecessary.
