Use unmodified tickprocessor.js in external wrapper

[sidorares]

It's currently quite painful to update tickprocessor.js from latest v8

Suggestion: have tickprocessor-wrapper.js which requires all other files, creates wrappers for os.system and read file and then vm.runInNewContext unmodified tickprocessor.js source

Not sure if it's easy/possible as there are streaming file reads and async execs
