remove dev dependency: derequire

[alxndrsn]

Ref https://www.npmjs.com/package/derequire

Not obvious why replacing require(...) with _dereq_(...) is useful.

[alxndrsn]

This might be important - PR changed to draft until the reason for _dereq_ is known.

Maybe:

• Can you explain the use case of this derequire module calvinmetcalf/derequire#25
• Why is derequire useful? calvinmetcalf/derequire#22

Hi @alxndrsn this looks promising to me.
Do you feel comfortable to mark it ready for review?

I'm still not clear what the intention was for derequire, or if it has any effect, but if you want to review it... #YOLO

derequire was used to transpose node's require() to a browser friendly format (_dereq_ by default).

We have replaced all require calls with ES module import in every module, we ship to browsers.

last occurrences can be found in source of pouchdb-adapter-leveldb and pouchdb-for-coverage packages:

• in LevelDB: requireLeveldown.js, and migrate.js
  (LevelDB is about to be removed: #9163)
• in Coverage: just for nodejs, because it uses module.exports
