Print cwd in verbose output

[bytestream]

The below changes cwd depending on gulp.src path. In the output it's not clear which path the command ran on.

    return gulp.src([
            'composer.json',
            'app/Requirements/composer.json',
            'app/Plugins/*/composer.json',
            'app/Widgets/*/composer.json',
        ], {read: false})
       .pipe(shell([
            'composer install -o '
        ], { cwd: '<%= dirname(file.path) %>', templateData: { dirname: path.dirname }, verbose: true }))

I think it would just be a simple case of updating https://github.com/sun-zheng-an/gulp-shell/blob/master/index.ts#L69 to include the cwd line lower down
