I had the same problem and stumbled on a fix by replacing #include "cstring" with #include "string.h" in serialbuffer.cpp

[ZZ-Cat]

cstring is a C++ header, and string.h is a C header.
As a temporary workaround, you MAY use string.h in place of cstring. However, this is NOT RECOMMENDED because CRSF for Arduino is written in C++ (specifically C++23), not C.

I am not going to fix this straight away, as I have higher priorities with CRSF for Arduino.
For example: As my work with #138 progresses, this issue could resolve itself on its own while I clean up the code-base.

Currently, I have taken time off of all of my public facing projects and I will not be back until early 2025. In the meantime, I may check-in from time-to-time, and triage issues, but that's it for the time being.
