Add an option to read sourcemap

[ooflorent]

Adding an option to access the source map would ease the integration with build tools.
e.g.:

const {code, map} = optimizeJs(input, {
  sourceMap: true,
  extractSourceMap: true,
})

My bad, yes, this should be supported!

+1, this is really important for vigneshshanmugam/optimize-js-plugin too. Thanks!

Looks like this issue ties directly to #25, which seems to be stuck on implementation decisions.

Rough tl;dr: optimize-js uses https://www.npmjs.com/package/magic-string under the hood, but doesn't pass any options and only returns the parsed code. Looks like the current ideas are to return either a MagicString instance or a Map object, but that would definitely be a breaking change.

Doesn't look like it's gonna happen.
