v1.0.0-rc.22

The App can now report its own errors and step timings, separately from any study, when the
participant agrees.

• Opt-in debug information. On first launch the App asks whether to share debug information
  with its developers through PostHog; nothing is sent before the participant agrees, and the choice
  can be changed at the bottom of the main screen. Events name fixed App steps (import, setup
  steps, start, pause, resume, complete, withdraw, category switches, export, startup), their
  outcome category and duration, export phase durations with coarse event-count and 50 MB size
  buckets, and uncaught errors by exception type and stack frames. They never carry study data,
  survey answers, configuration content, study or experiment IDs, the installation code, or error
  messages. Session replay, screen-view and deep-link capture are off.

Updating from RC21: install the newer APK over the existing app. Study data, configurations
and choices are unchanged; the debug-information question appears once after the update.
