send very large JSON response

[marchingband]

Hello, I'm using AsyncJsonResponse * response = new AsyncJsonResponse(true); to send a very large JSON array response of almost 500k. Smaller responses work, but with 500k I get pcb is NULL, and no data is sent. I am using WROVER module, so I have lots of psram available.

Is there anything i can tweak in your library to allow me to stream this many characters in a response? Is there another approach possible that I am missing?

I have had success printing this same JSON to a string in memory, and then using request->beginResponse() to send it in chunks, but I want to switch to a streaming approach to save memory.

If I can find a way to solve this, I would be happy to contribute a PR, so others can enjoy the ability to work with very large JSON data.

Thank you!
