An update with support for multiple aircraft decks, JustFlight F28 and a new AI voice provider

Self-Loading Cargo v1.6.5.8 has released and in this version there a number of new features.

Firstly, there is now proper support for "multiple deck" aircraft layouts for aircraft such as the Airbus A380 and Boeing 747. Passengers and crew will now traverse the aircraft stairwells to switch between decks while they board and deboard rather than spawning onto the deck directly.

Secondly, those of you on the Discord server may have noticed a post regarding Play.HT (one of our supported AI voice providers). Unfortunately, their service appears to have stopped working after they were acquired by Meta - completely unannounced. For that reason, I have disabled the Play.HT functionality within Self-Loading Cargo and will re-enable it if/when it becomes available. 

On a more positive note however, I have implemented support for the Cartesia.AI API Service which offers an equivalent product - and as an added bonus, they offer 20,000 FREE characters per month, with a very affordable subcription package starting from only $5 a month if you're inclined to support that platform. Simply sign up, generate an API key and copy+paste it into Self-Loading Cargo to start using the AI voices with your Captain and/or Cabin Crew. ElevenLabs.io support is unaffected and still works just fine.

Thirdly we have integrated support for the JustFlight F28 addon for MSFS - thanks to @Robles for the help with that.

And lastly you should notice a significant speed increase when using Self-Loading Cargo if you regularly open and close the different windows within the application. 

Of course there are also some minor bug fixes included, thanks for feedback from the previous versions.

Enjoy :-)
