Describe the request

The *.proto files in this repo are currently licensed under GPLv3. I'm not a lawyer, but that seems like it would prevent any non-GPL application from interacting arduino-cli over the gRPC interface because the application would need the *.proto files for code generation. Is that intentional, and if not, would it be possible to change the license for *.proto files specifically to something more permissive like MIT? It's seems strange that an MIT licensed application, for example, would be allowed to interact with arduino-cli over the CLI interface, but not the gRPC interface.
