Add a replayability-check tool

[katzuv]

Is your feature request related to a problem? Please describe. There is no streamlined way currently to check whether the code is replayable.

Describe the solution you'd like A tool that determines whether robot code is replayable. An implementation I thought of is to take a log file and replay it without changing any code. The tool will check whether real outputs fully match replay outputs.

This could also be built into AdvantageScope instead, a "check replay button on the file submenu could check a log files Real outputs and replayed outputs and highlighting any differences, or displaying a success.
