rewrite redot on top of ts-graphviz

[ChristianMurphy]

• replace custom grammar and stringifier with ts-graphviz
• use jsdoc based typescript
• align with unified toolchain
  • drop lerna in favor of npm workspaces
  • replace custom eslint with xo
  • use remark-preset-wooorm for markdown linting
  • remove precommit hooks
• upgrade unified version
• add tests
• upgrade CI
• move common documentation (contributing, code of conduct, etc) to .github repo

TODO:

• [ ] update documentation
  • match unified format
  • document ESM only
  • include more examples
• [ ] resolve remark-lint warnings
• [ ] add new redot-svg or redot-stringify-svg package?

/cc @wooorm and @remcohaszing if you have a moment, another set of eyes to review would be appreciated

[wooorm]

let me know when you need a another review, perhaps when docs and such are done?
