feature request :在尝试使用aos-tools编译tflite_micro_speech_demo例程时失败，提示缺少echo_canceller.h,o such file or directory 33 | #include "echo_canceller.h"等头文件。目标硬件是haaseduk1。请问是什么原因，如何解决？
运行环境: aos-tools 1.1.43
固件版本: aos release 3.3.0

### Version

rel_3.3.0 (Main)

Reproduce the aos-tools build for tflite_micro_speech_demo on haaseduk1 using aos-tools 1.1.43 and AliOS-Things rel_3.3.0. Start with the reported echo_canceller.h include failure and trace the example's build inputs; done means the demo compiles without missing-header errors.
