Optimize mix function for different labware

ET 3.
Change the way you mix depending on the thing you're mixing on
+ I think for the 2 mL tubes we want to look at the current solution height and the dead volume height, calculate two (?) intermediate heights between them, and mix at the bottom, intermediate heights, and just below the current height twice (?) at each height
+ For the 15 mL tubes maybe it’s 4 (?) intermediate heights while making sure we don’t submerge the top of the tip
+ I’m not convinced pipette mixing the 50 mL tubes is going to work well enough to implement
+ For 48/24 well plates, in addition to choosing a couple heights we probably need to offset the position from the center of the well and determine the minimum height of mixing
