使用com.alibaba.fastjson2.JSON#writeTo(java.io.OutputStream, java.lang.Object, com.alibaba.fastjson2.JSONWriter.Feature...)序列化大对象（数组，200M）时会出现OutOfMemoryError，查看是因为MAX_ARRAY_SIZE限制为64M。请问为什么是限制64M呢，可以修改这个值吗？

新增加一个JSONWriter.Feature.LargeObject，启用后就可以写大于512M的对象，请帮忙用2.0.16-SNAPSHOT帮忙验证，2.0.16版本预计在10月30日前发布

限制64M是为了有一些循环引用的场景导致内存占用过大的保护措施

2.0.16-SNAPSHOT使用JSONWriter.Feature.LargeObject写大于200M的对象没问题。感谢！
