i tested 8- and 96-channel pipetting into a 384 well plate and looks good. However, a single channel column selection selects 2 at a time which i'm not sure is expected?

Tested this out with all 3 pipette configurations and it works as expected! I'll follow up with this ticket https://opentrons.atlassian.net/browse/PLAT-344 to adapt logic now that the length of the sourceWell and destWell arrays are no longer equal to the number of wells actually selected.
