Refactor OptionValue to return a std::optional instead of taking a fail value. This allows the caller to handle situations where there's no value, instead of being unable to distinguish between the absence of a value and the value happening the match the fail value. When a fail value is required, std::optional::value_or() provides the same functionality.
