Open latest Result

[StefanVahlgren]

Previous results can be loaded from the result.log file and used to print it as as a summary or to show it with the ResultChart.

It would be very convenient if you didnt need to specify the exact location for the file if you want to load the latest one. Something like this would be possible to implement:
Result r = new Result(Result.latest("testresults/myLoadTest"));

This makes more sense to version control as well when you build your loadcoder tests, rather than to mistakenly saving somehitng like this:
Result r = new Result(new File("testresults/myLoadTest/20210202-130000/result.log"));
