feat: Allow aspirating more than the official maximum tip volume

[SyntaxColoring]

Overview

Officially, Opentrons 200 µL filter tips can only hold 200 µL. If you aspirate any more, you risk the liquid touching the filter.

However, our Applications Engineering and Science teams sometimes find themselves wanting to break past this limit. Depending on liquid viscosity, flow rate, and gantry speed, they've found that those tips can actually hold up to ~235 µL.

To use that extra capacity, they have to deliberately load the tip rack wrongly as an opentrons_96_tiprack_300ul instead of an opentrons_96_filtertiprack_200ul. This is a hacky workaround, and it makes things confusing by presenting the wrong labware in the deck map in the Opentrons App. We should provide a real way to do it.

Acceptance criteria

• By default, it's still an error if you try to aspirate past the official maximum volume.
• Within a protocol, there's some way to manually override the limit and aspirate more than the official maximum.
• This is gated behind an apiLevel version bump.
• Documentation warns users that if they do this, they're responsible for keeping the volume within bounds, and if they're not careful, they can contaminate the tip filter or the pipette itself.

Possible implementations

• aspirate() gains a parameter like ignore_tip_maximum_volume: bool = False?
• Complex commands like transfer() gain a tip_maximum_value_override: Optional[float] = None parameter, or something?
• Or maybe you override the volume at the tip rack level, like tip_rack_200ul.maximum_volume = 235?

Not a bug

For the non-filter tips, you can extend the volume range even further. The p300 pipette tips can actually hold about 440 ul before the liquid contacts the pipette. The p20 pipette tips hold about 70 ul. So there's a lot of room to allow for volume above the recommended maximum (assuming the pipette piston could accommodate it).
