Add streaming support for @ minecraft/server net module

I made this suggestion because I am trying to use this module to create a dialogue plugin for networked AI, but I found that this module does not support streaming, which means that the plugin needs to wait for the AI inference server to input all the text before the text is transmitted to the Bedrock version server in one go. This is quite bad because the current streaming technology is quite mature, but the @ minecraft/server net module, as a networking module, still cannot achieve this. Therefore, I hope to add streaming support for the @ minecraft/server net module.
