Feature: Stack traces

  Rule: Source maps are respected when dealing with transpiled support code

    Just-in-time transpilers like `@babel/register` and `ts-node` emit source maps with
    the transpiled code. Cucumber users expect stack traces to point to the line and column
    in the original source file when there is an error.
