feat: remove lodash as a dependency (#2378)

This will reduce the bundle size by ~23%(117kb).

Only 4 methods were used `flatten`, `flatMap`, `omitBy`, and `groupBy`.

`omitBy and `groupBy` were recreated while the es2019 implementations of
`flatten` and `flatMap` are used.

`lodash` is still used in the tests which is fine because it makes the
tests cleaner.

Closes #2118
