Turns out this was an error from my side, namely I was not interpreting the documentation correctly.

The correct types are:

- `ETS.KeyValueSet.set_options()`
- `ETS.KeyValueSet.t()`
- `ETS.table_identifier()`

This was more apparent from reading the [source code](https://github.com/TheFirstAvenger/ets/blob/c1689f289bd86e2867278f92e91a93699cdfb6f4/lib/ets/key_value_set.ex#L51-L55) as posted in this thread:
