OTA Updates/AirTag

Several "builds" have identical firmware and the only difference is Info.plist setting a different deploymentLimit for incremental rollout (what percentage of AirTags should get the update installed).

Starting with 1.0.301, Apple released only one build with predefined dates, included in the Mesu XML file, that the incremental rollout will happen on.
