Parser can't handle single quotes (instead of double quotes)#160

Description

data := "{'value':'data'}"
str, err := jsonparser.GetString([]byte(data), "value")
if err != nil {
	fmt.Print(err)
} else {
  fmt.Print(str)
}

This example fails to find the key "value" because it is surrounded by single quotes instead of double quotes. Even though "technically", they should be double quotes, it'd be nice if the parser handled single quotes interchangeably.

    That's not valid JSON, keys and sting values must be surrounded by double quotes:

    That's true, but in programming languages, especially when trying to encapsulate JSON or other strings, single quotes and double quotes are used interchangeably. It would be nice for the library to support it.
    …

    Well, that’s just not a good practice.

    Implemented in v1.5.0 — single-quote support is now available via the Config struct: Lenient.Get(data, "key") parses {'key':'value'}. The default remains strict (RFC 8259 double-quote only). See: https://github.com/buger/jsonparser/releases
