Title: Source range computation implementation for the SASS parser

NB: This branch is based off of `sourcemap_fix_relpath`, otherwise it would not make any sense.

Sourcemaps can now be constructed for nodes built while parsing SASS (`engine.rb`). A few fixes to the existing code have been made. All SCSS sourcemap tests have received their SASS counterparts.
