Obsolete version of APCA

[Myndex]

Hi liriliri, I just thought you'd want to know that the constants for the APCA version that you have in this tool are substantially obsolete. In file: src/dom-highlighter/overlay/ColorUtils.ts

The current APCA is available as an NPM package:

npm i apca-w3

Or you may want to visit the repo here on GitHb: https://github.com/Myndex/apca-w3

Please let me know if you have any questions!
