Add a progress bar for tracking status in Impact-T

[ken-lauer]

Impact-Z support already has this, as in:

lume-impact/impact/z/run.py

Lines 404 to 409 in 7623547

	with _maybe_progress_bar(
	progress_bar,
	total=len(self.input.lattice),
	leave=False,
	) as pbar:
	execute_result = run()

@ChristopherMayes requested that Impact-T also have an (optional) progress bar to more easily visualize the tracking state.
