Create Brain Slosher Instrument Class

## Requirements:
* use the `SY01B` class from the runze-control package: [example](https://github.com/AllenNeuralDynamics/runze-control/blob/main/examples/sy01b/connect_and_log.py)
* use dependency injection (i.e: pass in sub-hardware-components into the `__init__` as parameters) to keep the design modular.
* ensure that the class is thread-safe so that methods can safely be called by one-liner.
* Might depend on https://github.com/AllenNeuralDynamics/brainwasher/issues/32
* derive from a base class shared with the `Brainwasher` class.
* depends on: https://github.com/AllenNeuralDynamics/brainwasher/issues/31
* implement `start`, `pause` functionality
* implement a `run_step` function with required wash parameters exposed.
