Recursive updated_copy() of nested components with path

[tylerflex]

Enables

new_simulation = simulation.updated_copy(size=new_size, path="structures/0/geometry")

to recursively perform

new_box = simulation.structures[i].geometry.updated_copy(size=new_size)
new_structure = simulation.structures[i].updated_copy(geometry=geometry)
new_structures = list(simulation.structures)
new_structures[i] = new_structure
new_simulation = simulation.updated_copy(structures=new_structures)
