@@directive should be emitted on the first line, above header comment

[aspeddro]

ReScript: 10.1.4 and 11.0.0-alpha.3

One use case: emit shebang on first line. Node throws a syntax error. Apparently shebang should be on the first line.

@@directive("#!/usr/bin/env node;");

Js.log("Hello")

Compiled:

// Generated by ReScript, PLEASE EDIT WITH CARE
#!/usr/bin/env node;


console.log("Hello");

export {
  
}
/*  Not a pure module */

node src/directive.bs.mjs

file:///home/pedro/Desktop/learning-rescript/src/directive.b
s.mjs:2
#!/usr/bin/env node;
^

Thank you for filing! Check list:

• Is it a bug? Usage questions should often be asked in the forum instead.
• Concise, focused, friendly issue title & description.
• A minimal, reproducible example.
• OS and browser versions, if relevant.
• Is it already fixed in master? Instructions

@aspeddro that should be pretty easy to do. Want to submit a PR and try it out?

I am going to try.
