@Supereg I have made some further improvements on #120 to improve test stability & the overall deployment setup.

Wanted to follow up on the current state of the Accessory Setup PRs; most of them seem close to ready. Might not be a high priority but could be cool to merge it at some point in the future to close the PRs and tag more stable releases around these features.

Thank you for merging the deployment improvements. The PR is roughly ready. However, we haven't touched migration yet which is important if you are upgrading from previous installations or previous iOS installations. As soon as you opt into AccessorySetupKit you can no longer access previous Bluetooth devices and you need to migrate. The migration step is a bit finicky (according to documentation) where you must make sure that this happens before the CBBluetoothCentral is initialized the first time. At the same time, this presents a picker view from AccessorySetupKit which should not interfere with with the applications content. We haven't defined this step yet, therefore, some work might still be required here 👍
