GSOC2025: Json Library for D, weekly update #5

[Gaofei Qiu]

Clean up the codes of static array desirialization.
The codes of dynamic array still need revisions, because the 
current code is  deserializing to an appender, not deserializing 
to the array.
```d
     size_t elementCount = 0;
     while(true) {
         // Add a default element to the array so we can 
deserialize into it
         app ~= typeof(item[0]).init;

         // Create a temporary array that includes this new element
         auto tempArray = app.data;

         policy.onArrayElement(tokenizer, tempArray, elementCount, 
context);

         // Update our appender with the modified last element
         app.data[elementCount] = tempArray[elementCount];

         elementCount++;

         //get the next token
     }
```
