Feature request: --no-split flag to disable splitting regardless of config

[kfot]

Hi,

I’d like to request a new CLI flag for pytest-split similar to how pytest-cov implements --no-cov.

Sometimes it’s useful to temporarily run the full test suite without splitting, even if pytest-split is configured in pytest.ini or other configuration files.

Thanks for consideration.

This would be useful for when running in the CI with --lf flag so in case of a re-run only failed tests should run which means that they form a group themselves and the split isn't necessary anymore, therefore, would be nice to have a way to conditionally decide if perform the split or not.
