feat(client): Remove pipeline operations from FireflyClientPy

This commit removes the pipeline-related function definitions from the `FireflyClientPy` class in the `README.md` file. These functions are no longer needed in the Python client as pipeline operations are handled differently.

The removed functions include:

- `SetPipelineMode`
- `SetBatchSize`
- `FlushPipeline`
- `GetQueuedCommandCount`
- `IsPipelineMode`
- `GetBatchSize`
