v2.0.0

Changes

• Internal modularisation: moved the internal implementations of bugsnag-android-performance to the bugsnag-android-performance-impl module, and much of the API into the bugsnag-android-performance-api module. No changes are required to your dependencies and no code-changes are required.
  #406
• New bugsnag-plugin-android-performance-named-spans plugin to track open spans by name, allowing you to easily retrieve them using BugsnagPerformance.getSpanControls(NamedSpanQuery("spanName"))
  #411

Bug fixes

• Stopped attempting to send CPU metrics when none could be collected for a span
  #404
