Sets a parameter as a slash command option from Discord.

The supported data types can be seen in SlashParameterResolver, more types can be supported by implementing it.

Display name

Option names can be inferred from the parameter's name, see the wiki for more details.

Order

Options have the same order on Discord and the method, however, required options must be placed first (i.e., not null, and without a default value).

If the options are unordered, they will be automatically ordered and logged.

Choices can be added by either their parameter resolver, or by the application command itself from implementing SlashOptionChoiceProvider.

Varargs

You can set this parameter to be a vararg using @VarArgs, multiple varargs are allowed.
