build: add Windows specific compile option for ssize_t (#24)

* build: add Windows specific compile option for ssize_t

Ensure compatibility on Windows by defining ssize_t as int for the gRPC plugin. This adjustment prevents potential type-related issues during compilation.

* chore: include string header for message handling

Ensure that the string functionality is available for improved message processing.
