Add facility to match lines in a folder of stack traces extracted from Android Vitals mobile analytics tool

This is fairly specific, nonetheless it'd be useful given Android Vitals now provides an easy way to copy the stack trace from a crash cluster and vitals scraper no longer works with the current UI of Google Play Console with Android Vitals. Here's one example of the stack trace copied. It does not include the meta-data (e.g. the device model, Android version, etc.) or the analytics so the data is incomplete in terms of being able to analyse it.
