A Fix for Mamba / yaml_cpp_vendor

[jeff-hykin]

Hello! Glad to see another researcher getting ros wasm in the web.

I was going to try to use this on an upcoming ros project, but I'm having a hard time getting the example publisher running.

This is a fork off of your PR (@IsabelParedes) thar gets it a lot closer to running. The yaml_cpp_vendor and mambda issues are fixed. But now I'm stuck on the following

rmw_wasm/wasm_cpp/include/wasm_cpp/tojson/tojson.hpp:3:10: fatal error: 'yaml-cpp/yaml.h' file not found

If you have any advice for how to get it running I'd appappreciate it
