Add vwr troughplate as trough

[har1eyk]

The VWR_1_troughplate_195000uL_Ub was defined as a troughplate. This PR adds it as a trough.

thanks for the PR!

what is the benefit of having it as a trough? we have traditionally modeled "1 well plates" as Plates with a single well and just named "troughplate". happy to be convinced for a new design

I want to complete more testing on this branch.

I need to aspirate from a trough. My legacy firmware (2009) will not accept a troughplate.

This produces error:

  await lh.aspirate(
            hiOrange_trough["A1"]*8,
            vols=[500]*8, 
            use_channels=ALL_CHANNELS,
            spread="tight",
            liquid_height=[4]*8,           
            )

ValueError: Resource is too small to space channels.

This PR was re-evaluated and found to be needed for legacy-firmware Starlets to aspirate from troughs.
