Support emitting both output formats

[jimbobmcgee]

Any chance we can have a switch to output both text and XML output for the same test run? e.g. text on stdout and XML to a file.

Alternatively, a PS script to convert the XML output back to the text output would be useful -- the on-screen format of the text output is file is much easier to read than the tab-separated file emitted by Process-Diskspd.ps1.

Thanks

Allowing multiple outputs seems like a nice & fairly feasible idea; zero or one to stdout, but allow optional file specification.
