Fixes #4205

KS4.1.2 added a new option, batch_downsampling. This changes the number of options, and breaks our implementation. This PR deals with it.

We could allow users to pass the batch_downsampling, but KS docs say: "In general, this should be left as the default (using all batches)". So maybe we shouldn't?

Hi, this fix seems to be quite important, as kilosort is used by many researchers. Our projects auto test units are continuing failing on spikeinterface=0.103.1 and kilosort=4.1.2.

I am wondering if the maintainance team can release an expedited release.

I'm ok in cutting a new minor release soon. We have some major PRs that refactor some aspects of the postprocessing module, but they can wait.

@chrishalcrow @samuelgarcia maybe next week for a 0.103.2?
