Method now returns the content of Json Arrays, if it is specified in Json Path as String. The start and end character is a square bracket. Any complex object in the array is returned as Json, so that you might get Arrays of Array or objects.

You might want to use the b_putblk function instead of strncpy since you don't manage the case where you don't have enough space in the trash buffer. The trash->size member should never be changed as well since it represents the buffer size, not the number of bytes written in it. Please update the "json_query" documentation as well.
