Feature Request: Sourcemap Path Transformations

Please provide an option to configure sourcemap path transformations like output.sourcemapPathTransform option that Rollup provides. Alternatively reuse the output.sourcemapPathTransform property if sourcemaps are enabled for css.

I just tried to implement the feature in my code and I realized you would need to expose sourcemapPath, like sourcemapPathTransform function in Rollup does…

@CxRes done, see transform from sourcemap options

Usage example:

styles({
  sourceMap: [true, { transform: m => (m.sources = ["virt"]) }]
})
