table: v7 regression: installation time is super slow

Describe the bug (required) We’ve recently upgraded from v6 to v7. Since that upgrade, our yarn installation awaits react-table’s @scarf/scarf dependency for a very long time (over 50s):

$ yarn
yarn install v1.22.4
[1/4] Resolving packages...
[2/4] Fetching packages...
info fsevents@1.2.12: The platform "linux" is incompatible with this module.
info "fsevents@1.2.12" is an optional dependency and failed compatibility check. Excluding it from installation.
info fsevents@2.1.3: The platform "linux" is incompatible with this module.
info "fsevents@2.1.3" is an optional dependency and failed compatibility check. Excluding it from installation.

[-/7] ⠠ waiting...

[-/7] ⠐ waiting...
[4/7] ⠐ @scarf/scarf
[-/7] ⠐ waiting...

It finally ends after over a minute: Done in 64.09s.

If I simply force v6 using yarn’s “resolutions”:

  "resolutions": {
    "react-table": "6.11.5"
  },

Installation is finished in 9.82s. Forcing v6 obviously breaks at runtime, but clearly shows the install time speed difference.

Should be noted the times above are with an up-to-date yarn.lock file and no node_modules (git clean -fdx between installation runs).

Provide an example via Codesandbox! (required) Irrelevant when discussion installation time issues, I guess?

Steps To Reproduce (required) It appears this behaviour is best seen in repositories with many dependencies. When I tested v7 on https://github.com/wixplosives/sample-monorepo, I could see a slowdown, but it wasn’t as severe.

Expected behavior (Recommended) Stay fast? 😃
