[Work Item] VssTester should export event logs in evtx format instead of xml

[Sureshbd]

Describe the work

VssTester should export event logs in evtx format instead of xml
Additional Context
Currently the script exports the logs in XML format which is tedious to analyze instead it needs to be in EVTX format.

I find it useful in .XML format as well, can filter it quickly in PowerShell.
If you change to .evtx, please also leave a copy in .xml format as well.
Thanks.

I fully plan on leaving the xml in the output. This allows the full data to be in the output where as the evtx contains only the message strings which requires you to have the same event decoder to interrupt it.
