Allow forcing the use of colors

[svallory]

Hi,

I'm developing a Figma plugin and the code runs on a sandbox with no access to window or process so although I'm using Chrome Dev Tools to see the messages, debug is not coloring them.

Also, I can't set environment variables, so I would like to useColor to true, like I'm using Debugger.enable('cva:*');

I was looking through the source code and it looks like the useColors IS exported. The problem is with the typings provided by @types/debug.

I'm going to fork the project and convert it to Typescript so I can use what I need. Are you interested in a PR converting to TS?

I can also PR just the correct typings and you can add it to the project.

In the mean time, for any Typescript coders, this can force debug to use colors:

// This is necessary because the typings are out of date on Jan 7th, 2023
// eslint-disable-next-line @typescript-eslint/no-unsafe-member-access, @typescript-eslint/no-explicit-any
(Debugger as any).useColors = () => true;

This custom debugger based on debug-js (part of metalsmith.js) demonstrates how you can assign fixed colors per channel (eg :warn, :info etc) & pipe the output to a file (Debugger.handle = fileLogHandler('my.log'))
