```
session.settings.Session.typed_option(self, name: &str) -> Result<Option<OptionValue>, Error>
```

Read one option, decoded according to what tmux declares about it.

A flag comes back as [`OptionValue::Flag`] and a number as
[`OptionValue::Number`], so a caller does not decide for itself that
`on` means one. Everything else, including user options, stays text.

# Errors

Returns an error when tmux does not recognize the option name.
