G7 cleanup

[Navid200]

Correcting some notes to show G7 when G7 is being used.
Adding G7 to the menu items that correspond to G7 as well.

This is tested.

Overall I think this is useful but I don't really like the logic too much because I think you're going to potentially have problems in the transition between when the sensor is active before and after firmware information has been read. Can you modify isDeviceG7() to simply check for 4 digit tx_id ?

[Navid200]

Can I open another PR to change "G6/Dex1 Support" to an array allowing 3 options (G5, G6/Dex1, or G7)?
Then, instead of looking for the number of characters in the transmitter ID, we can look at that setting.

I will test transitions and everything.
After that is merged, this PR will become simpler.

[Navid200]

Consider that in the future, we may have other devices that use a 4-digit transmitter ID.

[Navid200]

I did the change.
If you approve adding a specific selector for G7 later, I will then replace these with conditionals on the selector.
But, for now, this should be good.

Will be tested before tomorrow.

Tested with a G7.
Looks good.
Everything looks as shown in the screenshots above.

Looks like it should work other than if AAPS is fussy about the data source name but if so hopefully that can be resolved.

change to "G7 Transmitter";

[Navid200]

G7 transmitter and sensor are together. There is no reason to call it a transmitter any longer. It is valid to call it a device to avoid calling it a transmitter.
