Add option to add space between CSS selectors

Description

This is the default template for feature requests. I don't see any option to set space between the CSS selectors like: No space: a,p,b{} Yes space: a, p, b{} So, it'll be awesome if you add this feature too.

NOTE:

• Do not include screenshots! This library is a text processor, we need text inputs and outputs for debugging and fixing issues.
• Check the list of open issues before filing a new issue.

Input

With this new feature, when I give like this input:

#main,#section, a {
  color: blue;
}

Expected Output

I'd like to see this output:

/*When the option is true*/
#main, #section, a {
  color: blue;
}
/*When the option is false*/
#main,#section,a {
  color: blue;
}

Environment

OS: Android => Chrome
