`jstream` is a streaming JSON parser and value extraction library for Go.

Unlike most JSON parsers, `jstream` is document position- and depth-aware -- this enables the extraction of values at a specified depth, eliminating the overhead of allocating encompassing arrays or objects; e.g:

Using the below example document:

        }
        return builder.toString()
    }

    def format(Node node, Appendable target, int depth, boolean prettyPrint, boolean indentSelf) {
        if (node instanceof Element) {
            Element element = (Element) node

            if (indentSelf && depth > 0) {
                target.append('\n')
                depth.times { target.append('    ') }
            }

            target.append("<${element.tagName}")
