Usage

Usage: ./time-diff-output.sh [-l low] [-m medium] [-h high]
  -l, --low                   Threshold in seconds for low duration color formatting
  -m, --medium                Threshold in seconds for medium duration color formatting
  -h, --high                  Threshold in seconds for high duration color formatting
  -r, --reset-mark            String match to reset total counter
  -p, --parse-fastlane-date   Parse date from fastlane output

Example: ./time-diff-output.sh --low 10 --medium 30 --high 60 --reset-mark "Step: " --parse-fastlane-date
