Single quotes in double quoted strings lead to maximum call stack

[clarencejychan]

Hi there!, I'm currently using your HOCON parser and noticed that there is a bug with single qutoed strings not being escaped.

Given a HOCON such as

x = [
    {
        s : "'Hello'"
    }
]

you'll run into a

RangeError: Maximum call stack size exceeded
    at m (index.js:255)
    at m (index.js:262)
    at m (index.js:262)
    at m (index.js:262)
    at m (index.js:262)
    at m (index.js:262)
    at m (index.js:262)
    at m (index.js:262)
    at m (index.js:262)
    at m (index.js:262)

I've solved the problem by escaping the characters myself with Regex prior to parsing, but just as an FYI.

Thanks!
