A typed option write that tmux's option table refuses, so nothing was sent.

Raised by `set_typed_option` and its siblings before dispatch, never by
tmux, and the option is left as it was. [`crate::OptionValue`] says
which variant each kind of option takes. The value is not kept, as no
option value is; `reason` says what the option takes instead.
