make_epochs step fails if runs have different bads

[hoechenberger]

I'm handling EEG data where bads may vary from one block ("run") to another.

I'm seeing the following problem when running preprocessing/make_epochs:

│23:10:33│ ❌ sub-184 A critical error occurred. The error message was: epochs[1].info['bads'] must match

Aborting pipeline run. The traceback is:

We should probably use unify_bad_channels()?
