Update the JsValue. Support only child and array slice operators.
An implementation of JSONPath that follows the semantics described by Stefan Goessner on his blog.
Adopt from https://github.com/josephpconley/play-jsonpath
This parser supports all queries except for queries that rely on expressions of the underlying language like $..book[(@.length-1)]. However, there’s usually a ready workaround as you can execute the same query using $..book[-1:].
One deviation from JSONPath is to always flatten the results of a recursive query. Using the bookstore example, typically a query of $..book will return an array with one element, the array of books. If there was another book array somewhere in the document, then $..book will return an array with two elements, both arrays of books. However, if you were to query $..book[2] for our example, you would get the second book in the first array, which assumes that the $..book result has been flattened. In order to make recursion easier and the code simpler, we always flatten the result of recursive queries regardless of the context.
