libtmux::Snapshot::take(backend: std::shared_ptr< const detail::Backend >, fields: std::span< const std::string_view >, request: CommandRequest, placement: FormatArgument = FormatArgument::flag) -> expected< std::shared_ptr< const Snapshot >, CommandFailure >
```

Run `request` with this entity's fields appended and parse what came back.

Rows are parsed once, here: entities hold views into them, so a second parse would invalidate every entity already handed out.
