Manual rebase and sync upstream

[Sukka]

eslint-plugin-i seems to be up of sync from upstream for months:

A manual rebase is required.

---

The object.groupby package can be replaced with this:

// This is a **non spec compliant** but works in practice replacement of `object.groupby` package.
const groupBy = (array, grouper) => array.reduce((acc, cur) => {
  const key = grouper(cur);
  (acc[key] = acc[key] || []).push(cur);
  return acc;
}, {});

And object.fromentries can be replaced with const { fromEntries } = Object;

Thanks for reminding, I'll do it tomorrow.
