Update GCClassic benchmark statas output to spreadsheet format

gcpy/benchmark/modules/benchmark_gcclassic_stats.py
- Add 2 blank columns after "Wall Time"
- Add 2 blank columns after "CH4"
- Remove "blank" after "Mean OH"

This now allows you to cut-n-paste the output into the Google sheet
and then pick Data -> Split cell into columns.
