    Re-adds tips to the tip tracker
    This method should be called when a tip is dropped in a tiprack. It
    should be called with ``num_channels=1`` or ``num_channels=8`` for
    single- and multi-channel respectively. If returning more than one
    channel, this method will automatically determine which tips are
    returned based on the start well, the number of channels,
    and the tiprack geometry.
    Note that unlike :py:meth:`use_tips`, calling this method in a way
    that would drop tips into wells with tips in them will raise an
    exception; this should only be called on a valid return of
    :py:meth:`previous_tip`.
    :param start_well: The :py:class:`.Well` into which to return a tip.
    :type start_well: :py:class:`.Well`
    :param num_channels: The number of channels for the current pipette
