Description of the bug

Initializing a Simulation object requires fetching the entire mesh because of Simulation._units["distance"] , see https://github.com/ansys/pydpf-post/blob/ea886a391276c5ff0743eb3162cc25536d4f6fc3/src/ansys/dpf/post/simulation.py#L86

For large models, this makes the initialization very slow.

Steps To Reproduce

from ansys.dpf import post

path = r"<path/to/large/model>"
simulation = post.load_simulation(path)
