Question: Is `WriteCallback` asynchronous? #1023

I'm curious how WriteCallback functions exactly. If send multiple requests synchronously with a WriteCallback, does cpr call WriteCallback in a separate thread? Or will my function block until each request receives a callback in order?

It's basically a wrapper around CURLOPT_WRITEFUNCTION. More information is available here: https://curl.se/libcurl/c/CURLOPT_WRITEFUNCTION.html
