  - Some log processing is done:
    - better date time format
    - string interpolation
    - 'testName' property added
  - Depends on an xunit file, should be left over from every test run

  Examples:
  ${chalk.green('crawfish.mjs | jq -SC | less -R')}
    - jq -SC will sort the keys and force color output
    - less lets you page through and search logs

  ${chalk.green('crawfish.mjs | jq -Sc | code -')}
    - jq -Sc will sort the keys and keep the logs one line (compact)
    - Opens the output in vscode, good for searching!
