Extending Select Prompt to Support KeyValuePair

[jwsadler]

Currently the select prompt only supports simple types, it would be great if there was a specialized version that allowed for a key and a description. So that when checking what was selected we can go by the key value rather than a description.

Hey, maybe it's not exactly what you want to use but you can try using the UseConverter method: https://spectreconsole.net/api/spectre.console/selectionpromptextensions/c6320835 . Basically, given the key, you can decide how the text renders in the screen.

This is a small example in how I used it:

var keySelection = console.Prompt(
    new MultiSelectionPrompt<int>()
        .Title("Select the API keys to delete")
        .PageSize(10)
        .NotRequired()
        .AddChoices(account.APIKeys.Select((_, i) => i))
        .Select(account.SelectedAPIKeyIndex)
        .UseConverter(keyIndex =>
        {
            var key = account.APIKeys[keyIndex];
            return $"{key.Name}: {key.Key.Value}";
        })
);

Like @jmigual points out, the UseConverter is what you're supposed to use in this situation.
