Flank should record fatal exception outcome and or details from a matrix execution

Hello,

I've noticed that when a Fatal exception occurs on Firebase Test Lab (e.g,
These are simply recorded in the matrix_ids.json file as {"outcome": "failure"}. For the purposes of daily reporting on test executions, I would love if Flank were to capture any other keys indicative of crashes when they happen. I know this is possible through the Cloud Tool Results API, but I would like if Flank could do that, as we simply parse artifacts. Even if it's a simple boolean from FailureDetail ({"crashed": true}) that would be helpful.
