[MNT] - Warning on scipy.stats.mode

[TomDonoghue]

As of scipy version 1.9.0, there is a new 'keepdims' argument in scipy.stats.mode that needs to be set for future-proofing, and will start to fail in scipy version 1.11.0: https://docs.scipy.org/doc/scipy/reference/generated/scipy.stats.mode.html

This relates to the use of scipy.stats.mode here:
https://github.com/HSUPipeline/convnwb/blob/main/convnwb/timestamps/align.py#L168

For future scipy usage, this could be updated to:
ixis_mode = stats.mode(ixis, keepdims=True)[0][0]

Or, equivalent updates:
ixis_mode = stats.mode(ixis, keepdims=True).mode[0]
ixis_mode = stats.mode(ixis, keepdims=False).mode

Basically - the fix is easy, but need to decide whether to enforce a specific version of scipy, and/or do a version check.

sync_behav_out, sync_neural_out = match_pulses(sync_behav, sync_neural, n_pulses=500, start_offset=100)
Change start_offset number has a significant effect on the output

This is now fixed, by adding a version check, so both old and new scipy versions should work.
