Just prepping release notes.

Release notes:

• Fix: Explicit tests should be marked as Skipped. See https://github.com/spekt/nunit.testlogger/issues/86
• Replace Test Case name parser Possible Breaking Change
  • For most or maybe all users the new parser should fix the issues shown below, without introducing new issues. In case you do encounter any new parsing failures a feature flag Parser=Legacy has been added to use the prior parser. See logger config wiki for details.
  • Fix: Test case parse error if name contains special characters. See https://github.com/spekt/nunit.testlogger/issues/90
  • Fix: Covers several parsing issues. Thanks @becha2 for all the detailed examples. https://github.com/spekt/testlogger/issues/28
  • Fix: Log member data. Thanks @BottlecapDave for the issue report and @hach-que for the draft fix. https://github.com/spekt/junit.testlogger/issues/50
  • Fix: Issue parsing chars. Thanks @binarycow for the issue report. https://github.com/spekt/nunit.testlogger/issues/90
  • Reduce log verbosity: The parser, if it encounters problems, will only output one warning per run to the console instead of one per problem
