      mod_src_bytes : bytes
          The content of a tarfile which contains the TVM-generated sources which together form the

          into a directory and the sources compiled into a MicroLibrary using the Compiler.
  
      template_project_dir: str
          The path to a template microTVM Project API project which is used to generate the embedded
          project that is built and flashed onto the target device.
  
      project_options: dict
          Options for the microTVM API Server contained in template_project_dir.

          skips the project generation and opens transport to the project at the project_dir address.
