My Mitsubishi heat pump has a vane angle control on the remote.
Swing mode is not a control but rather, one of the possible states of the Vane.
The esphome mitsubishi heat pump integrations sets the vane to a fixed (undesirable) position whenever Swing_Mode is set to OFF.
The SwiCago libraries for the Mitsubishi heat pump properly define the Vane control, but there is currently no way to implement them because there is no trait to control the vane mode in HA.
It would be nice to have a vane_mode control that contains at least the following modes (from the SwiCago library):
`const char* VANE_MAP[7] = {"AUTO", "1", "2", "3", "4", "5", "SWING"};`
