Multi-Channel Accessory Grouping
* **Please explain your feature request in a one or two sentences.**
First of all, I just started using this plugin today. It works great and I'm thankful for the work you've done. I have other Meross MSS630 devices that are HomeKit Native, but purchased one that was not, and this gives me the ability to use it in HomeKit.

Currently, when you add a Native HomeKit Meross device, the main name for the device is not added as a separate accessory, it is a group that is added of the other accessories related to it, in my case outlets in the MSS630. There are three outlets that all have their own name and then the main display name is used to group them in HomeKit. They can be split by choosing to show as separate tiles, or as a single tile. 

As of right now, when your plugin pulls in devices, it pulls in the main display name as a separate accessory that is also turned on and off when any one of the other accessories is turned on or off or it can be used to turn them all on or off.

It would be nice to have them show up as a single tile in a group with the main name and give us the option to split them into separate tiles.

* **Is your feature request related to a problem? Please describe.**
There is no problem, it's just an aesthetically pleasing way to look at the tiles and for them to operate as a group.

* **Any particular Meross devices that this relates to?**
I believe this could possibly affect any multi-channel device.

* **Anything else?**
I also have the same issue as Issue #550, where the Native Ignore does not work for my Native HomeKit Outlets, they use the same firmware and hardware version as the issue lists:
Firmware: 4.2.2
Hardware: 4.0.0

The non-native device uses:
Firmware: 3.2.2
Hardware: 3.0.0
