build with sourcemapper

[tophf]

Stylus arguably needs source maps in order to report correct position of errors/warnings.
Hopefully the extra size isn't too big, I tried building this repo but got a bunch of errors for circular dependencies and whatnot.

What is sourcemapper? Can you repro the line number issue in the demo?

[tophf]

It's the feature that maps source line/column positions to the compiled output so Stylus extension can report correct errors in case parsing failed while building moz-sections from the compiled sourceCode.

Here:

Make sense, but sounds like a feature that will be rarely used.

It depends on source-map, which is 106kB uncompressed and 36kB minified according to bundlephobia.

Too big. We could try to add our own code that simply makes an array of positions, not a full-fledged sourcemap, I guess.
