extension request: preemptive multithreading lib for M0, M3, M4 (like std::thread, ftrias/TeensyThreads, ESP32)

hi,
coincidentally I found the lib ftrias/TeensyThreads https://github.com/ftrias/TeensyThreads, unfortunately working just for Teensys.
IIUC, it's not trivial to port that preemptive multithreading lib to standard Arduinos... :(
So what would be realy awesome is if there was such a std::thread implementation available for M0, M3, M4 Arduino/Adafruit cores!

首先审查所请求的 std::thread 风格行为和链接的 ftrias/TeensyThreads 库，然后将其假设与适用于 M0、M3 和 M4 的 Arduino/Adafruit core 进行比较。完成的标准应是为这些 core 提供受支持的抢占式多线程实现，但该 issue 没有指出文件或测试。
