Memory Problem based on ToString()

Having memory issues with the generated POJO based on SObject, the problem is the toString method, right now is printing the whole object and its dependencies when dealing with huge objects it's generating an overhead of memory usage

java code example:
```

public String toString() {
StringBuilder sb = new StringBuilder();
sb.append("[CustomObject ");
sb.append(super.toString());
this.toString1(sb);
sb.append("]\n");
return sb.toString();
}

```
template example:

```
@Override
public String toString() {
java.lang.StringBuilder sb = new java.lang.StringBuilder();
sb.append("[$gen.className$ ");
$gen.superToString$
$gen.splitMemberMetadataList: { split | toString$i$(sb);
}$
sb.append("]\\n");
return sb.toString();
}
```

Start by locating the generator template containing the shown toString implementation and trace how generated POJOs inherit or render SObject dependencies. Confirm the intended behavior for huge objects, then add coverage for the generated toString output and verify that it no longer creates the reported memory overhead.
