[turbolizer] Version bumps for dependencies

This CL updates TypeScript, rollup and d3 to newer versions.

Drive-bys:
 - Remove unused source file lang-disassembly.
 - Fix typing problem with FileReader callback

The rollup version update also ensures that watch mode works again:

  npm run-script watch
