Transform the location of error messages using source maps

[STRd6]

coffee build/main.coffee 
X [ERROR] Could not resolve "../pixie"

    lib/exports.coffee:3:21: <- !! This should actually be line 1
      3 │ ({version} = require("../pixie"));

The location of error messages comes from the compiled JS, not the CoffeeScript source. It makes jumping to the error slightly annoying.

Thanks for your comment! I'll look into it asap 🙏

I've just dug into why error locations from esbuild-coffeescript can be wrong, and was surprised to discover that the coffeescript compiler itself is causing this (at least in my case). If I run my example busted coffeescript file through the coffeescript cli, or the Coffeescript 'try' page, I get the same (incorrect) line number and column for the error - which was accurately reported in my esbuild output!
