[det]check_predicate_option(:PI, +Arg, +Option)

Verify predicate options at runtime. Similar to current_predicate_option/3, but intended to support runtime checking.

Errors: - existence_error(option, OptionName) if the option is not supported by PI.
- type_error(Type, Value) if the option is supported but the value does not match the option type. See must_be/2.
