/**
 * This code is designed to spawn a new shell process using either PowerShell or
 * bash, depending on the operating system of the host machine.
 *
 * The main benefit is color support, which is not available when using the
 * `child_process` module to spawn a new process.
 *
 * It will stream the output of the child process to the parent process, and
 * will also log the exit code of the child process when it exits.
 *
 * @param {string} command The command to run in the child process.
 * @param {object} options Options to pass to the child process.
