Feature/schema compiler error message

[JayImprobable]

Description

Originally, the RedirectedProcess responsible for compiling the schemas was set as

var exitCode = RedirectedProcess.Command(Common.DotNetBinary)
                        .WithArgs(ConstructArgs(projectPath, schemaCompilerPath, workerJsonPath))
                        .RedirectOutputOptions(OutputRedirectBehaviour.None)
                        .AddErrorProcessing(Debug.LogError)
                        .AddOutputProcessing(ProcessStdOut)
                        .Run();

This way, whenever a new error message was generated, Debug.LogError was called, creating several error messages on the Console.
What I did was:

• In the GenerateCode class I've created a private static string SchemaCompilingErrorMessage variable, where I store the complete error message.

        private static void SchemaCompilerErrorProcessing(string s)
        {
            SchemaCompilingErrorMessage = $"{SchemaCompilingErrorMessage}\n{s}";
        }

• Changed the RedirectedProcess to

var exitCode = RedirectedProcess.Command(Common.DotNetBinary)
                        .WithArgs(ConstructArgs(projectPath, schemaCompilerPath, workerJsonPath))
                        .RedirectOutputOptions(OutputRedirectBehaviour.None)
                        .AddErrorProcessing(SchemaCompilerErrorProcessing)
                        .AddOutputProcessing(ProcessStdOut)
                        .Run();

• Created the SchemaCompilerErrorProcessing function, which simply concatenates the error messages into the SchemaCompilingErrorMessage

• And finally, if there was any errors in the schema compiling, I call Debug.LogError(SchemaCompilingErrorMessage);, showing the single, concatenated error message
