Sourcemap support

[Cobertos]

Looks like this extension doesn't support sourcemaps? It looks to be supported by the upstream.

Here's a small example of it printing the wrong line number for an error.

Using this file (test.js) with some things that will definitely get transpiled:

import dayjs from 'dayjs';

const asdf = ()=>{
  // Just a dummy
  console.log("dummy");
};

const asdy = ()=>{

};

export const a = ()=>{ throw new Error('test'); };

... it will not provide the correct line number for the error when running a():
