[BASOP CI] Adding MLD parser based on junit report from @bohmr

Adding scripts/parse_mld_xml.py which uses report-junit.xml instead of report.html to produce the MLD report. The html parsing does not work for later versions of pytest and the xml parsing seems more robust. Further, the test names now includes the full name such that it may be given as an argument to pytest to rerun the test.

Not used in PC repo, so the addition of this file does not affect anything.
