Added
- Ability for `Choice` to display a custom message instead of the value being selected. This includes a new type alias (`Options`) which supports both the `Mapping[str, str]` and `List[str]` forms. ([389](https://github.com/plannigan/columbo/pull/389))
Deprecated
- The `OptionList` type for `Choice` in favor of `Options` ([389](https://github.com/plannigan/columbo/pull/389))
Fixed
- All exceptions raised by `columbo` listed in the docstrings. Improved phrasing to make messaging consistent.
