  Extend Backtraces to allow configuration of stack decoders
  
  Allow the user to overwrite the default stack-decoders in `Backtraces`.
  Users can then experiment with custom stack decoders, or tweak the
  output of the stack trace to their liking.
  
  We store the stack decoders for each of the supported backtraces in
  `DisplayBacktraceMechanisms` in a global `IORef`.
  
  When collecting `Backtraces`, we also ask for the currently configured
  stack decoders (specified via `DisplayBacktraceMechanisms`) and use them for
  printing the `Backtraces`.
