Gym-uds build in MacOS

[rval735]

Today I cloned your project in a MacOS environment, when the command ./build.sh was executed, it showed one error:

gym-uds-api$./build.sh 
./build.sh: line 2: realpath: command not found
usage: dirname path

Then another:

protoc not found!

Both were installed using brew:

brew install coreutils
brew install protobuf

Then, I had to install as well grpc for Python and C++

With all that, build.sh ran effectively.

Well, after all that, I just wanted to share the experience and possibly add as a note in the README.md a more explicit list in the Requirements section.

Or simply, just take the contents of the binding-cpp folder as is.

Thanks for reporting! Should be fixed in e495c9a. Feel free to reopen the issue if something is still wrong.
