Clarity and Job Fixes

Updated the README with clearer instructions and the correct way to run only the MEBT.

Fixed the GitHub workflow to make the working directory safe.

Included new quadrupole noise in the BTF.

Removed some unused lines of old code.

Safer PCASPY Importing

The PCASPY modules are now only imported once the server is started.

Type hint fix

Fixed type hints for the VirtualAccelerator and VirtualAcceleratorBuilder classes.

Adding Physics Nodes Fix

Fix to how physics nodes are added to the model when initializing the model.

Builder and Physics Devices

This update changes how the virtual accelerators are imported. There is now a builder class that allows for modifications before instancing the full virtual accelerator.

There are also now Physics devices and in OrbitModel Physics nodes. These return values not measurable by real diagnostics. These can be added to the current virtual accelerators using the new argument '--physics_nodes'.

Version 0.8.0: Importability

Virtual accelerators can now be imported into other scripts without starting an EPICS server. A new example script demonstrates the process.

Version 0.7.6: Virac Parser

This update added a new parser to Virac, allowing for better customization and automation of arguments when developing new beam lines.

Version 0.7.5: Pytest Integration

This update switches the GitHub workflow to use Pytest and removes the unused GitLab workflows.

Major update to v0.7.4

Supports main SNS accelerator, SNS BTF and a separate Injection Dump line.
