Simulate pulse and then simulate steady-state without needing to reinitialize scenario

[charlesbmi]

Describe the new feature or enhancement

As someone visualizing tFUS simulations, I would like to be able to easily visualize both a pulse simulation and a steady-state simulation.

Currently, the scenario needs to be reinitialized in order to run both simulations. For example:

import neurotechdevkit as ndk

scenario = ndk.make("scenario-0-v0")
result = scenario.simulate_pulse()
result.render_pulsed_simulation_animation()

(Pulsed animation is shown)

result = scenario.simulate_steady_state()

Estimated time to complete simulation: 44 seconds. Memory required is 8 GB (available 68.719476736 GB). These values are approximated.

File ~/mambaforge/envs/neurotechdevkit/lib/python3.10/site-packages/stride/problem/acquisitions.py:824, in Acquisitions.add(self, item)
    811 """
    812 Add a new shot to the Acquisitions.
    813 
   (...)
    821 
    822 """
    823 if item.id in self._shots.keys():
--> 824     raise ValueError('Shot with ID "%d" already exists in the Acquisitions' % item.id)
    826 self._shots[item.id] = item
    827 item._acquisitions = self

ValueError: Shot with ID "0" already exists in the Acquisitions

Describe your proposed implementation

Some possible ideas:

• Add a .clear() method that clears a previous Acquisitions
• Use a randomly generated hash (e.g., 49c2965) instead of "0" for the Shot ID to prevent conflict between new Shots

Describe possible alternatives

• Could just clear the previous data when running a simulation, but we may want to keep it for further analysis.
