Subject: [PATCH 1/2] Add stricter mypy type check flags

- Remove unused type: ignore.
- Remove asterisk import and add `__all__` with all exported names, to
  pass with the `no_explicit_reexport` mypy flag.
- Add various mypy config for developer ergonomics (prettier errors,
  printing error codes, warning about unused config, ignores and casts
  etc). Kept `warn_return_any = False` in `dacite.types` for now since there
  would have to be a lot of ignores/casts otherwise.
