描述

When you have a large array (let's say 1000 integers) that needs to be written out, it will be written out one int per line. It would be very useful to be able to specify how many items (or a max line length) are output per line to improve formatting and remove the need for a lot of CR's

e.g, with a max items per line of 10

{ "array" : [ 0,1,2,3,4,5,6,7,8,9 10,11,12,13,14,15,16,17,18,19 20,21,22,23,24,25,26,27,28,29 ], }

研究方向
The issue requests adding an option to limit the number of array items printed per line. To implement, look at the existing output classes (e.g., `StreamWriter` in `src/lib json/json writer.cpp`). The array writing loop (likely in `writeArray()`) currently prints each element on a new line. Add a member variable for max items per line, and modify the loop to insert a newline after every N items. Consider adding a setter method. Check for existing similar options like indentation width to follow the same design pattern. Ensure the feature is documented.
