Subject: [PATCH 1/4] feat: add necessary gems to introduce rbs to this
 repository

To add types, I would like to have help from typeprof to define rbs files for current library code that's why I added both steep and typeprof to Gemfile.

Subject: [PATCH 2/4] feat: add Steepfile with the minimum configuration

This file indicates that type definition files are placed in the `sig` directory and the actual implementation files that I want to define types for are located in the `lib` directory.
Additionally, it is configured to disable type error checking so as not to raise much errors.

Subject: [PATCH 3/4] feat: add processing.rbs as a type definition file for
 processing.rb

As a first step toward adopting rbs for this project, added type a definition for a simple method.
More type definitions will be added incrementally.
