Source map support

[ethul]

Raising this on purs-loader

See ethul/purescript-webpack-example#4

Update: we may need to specifically return the sourcemap:

this.callback(null, source, map);

Is there an example of using this feature? I tried adding sourceMaps to the pscArgs, based on the line here

purs-loader/src/source-maps.js

Line 26 in 5922309

const isSourceMapsEnabled = options.pscArgs && options.pscArgs.sourceMaps;

, but I got an error that it's an invalid option:

pscArgs: {
  sourceMaps: true
}

ERROR in Invalid option `--source-maps'

Usage: purs COMMAND
  The PureScript compiler and tools

Using codegen: "js,sourcemaps" seems to work to produce the map files in the output folder, but I can't get them to wind up in the dist/ folder when running webpack, or to work with the dev server. I tried using the source-map-loader as well, but the files don't seem to be recognized.
