No stack trace included when parsing invalid JSON

When throwing an error in json_parse, no stack trace is included. This makes it difficult to know where in a codebase an error is coming from. Perhaps the built-in Error class could be used [here](https://github.com/sidorares/json-bigint/blob/8208aa1352eba252b60756672ab7c17f300d6ccd/lib/parse.js#L148) instead?
