Refactor internal code about carol

Hi @uki00a, is there anything I can do to assist this? Do you have any broad plans for refactoring?

Hi @Regan-Koopmans, thanks for your comments!

Do you have any broad plans for refactoring?

I plan to do the following things:

• (high priority) chrome.ts is messy. I'd like to split this file into separate files (chrome.ts, request.ts, errors.ts, messages.ts, etc.)
• (low priority) simplify chrome.ts using puppeteer
  • calro, on which this module is based, uses puppeteer to provide more flexibility to users.
  • puppeteer/puppeteer#6433
