  Expose `StackTrace` and `StackSnapshot` from `Backtraces`
  
  Instead of decoding the stack traces when collecting the `Backtraces`,
  defer this decoding until actually showing the `Backtraces`.
  This allows users to customise how `Backtraces` are displayed by
  using a custom implementation of `displayExceptionWithInfo`, overwriting
  the default implementation for `Backtraces` (`displayBacktraces`).
