FIXME

Libre 3:
- Gen2 .getSessionInfo outpassed by new certificate data and ECDH ephemeral keys (whiteCryption's Secure Key Box)
AppleWatch:
- "How do I add 'com.apple.developer.bluetooth-central-background' entitlement for WatchOS?" (https://developer.apple.com/forums/thread/109947)
@AppStorage(selectedTab) prevents managing the "More..." fifth tab item

TODO

Apple Watch app: workout and extended runtime background sessions, complications, widgets
alarm snooze, public timers instead of SwiftUI private ones
scrollable graph, offline trend arrow, landscape mode, realtime RSSI
smooth the historic values and project the trend ones (see LibreTransmitter)
log: limit to a number of readings, prepend time, Share menu, record to a file, add Logger support
TabularData as persistence layer
