Is your feature request related to a problem? Please describe.
A clear and concise description of what the problem is.

Graphix does not guarantee the runnability and deterministic properties of a pattern when it is passed to a simulator or QPU. It would be beneficial if these fundamanetal properties are ensured during the pattern generation process.

Describe the feature you'd like
A clear and concise description of what you want to happen.

One possible way to do this is to generate a pattern from the underlying graph and flowlike objects(including causal flow, gflow, and pauli flow). Flows can be understood as a feedforward protocol that ensures deterministic property of MBQC.

1. Generalize the graph-based pattern generator(generator.generate_from_graph) with an arbitrary flowlike object(related to Add optional argument to pass gflow in generate_from_graph() #120 )
2. Generate every pattern through the above generator
3. Implement flags in the pattern class such as pattern.is_deterministic and pattern.is_runnable.

I plan to refactor some methods in the pattern class to clarify which operations preserve the properties. For example, standardize and shift_signals preserve the properties, but add does not. I will implement a property-preserving pattern concatenation method for those who want to directly edit the pattern.
