Minor: exception defined inside internal method

[raph-luc]

Quick question:

pyfluent/src/ansys/fluent/core/workflow.py

Lines 66 to 73 in 1e1416a

	def _new_command_for_task(task, session):
	class NewCommandError(Exception):
	"""Raised on an attempt to create command for a given task."""
	def __init__(self, task_name):
	super().__init__(f"Could not create command for task {task_name}")
	task_cmd_name = task.CommandName()

Isn't this definition for a custom Exception nested inside a non-public method kind of useless, in the sense that users won't easily be able to import and catch this NewCommandError? In which case this 5 lines definition could be replaced with just Exception(f"Could not create command for task {task_name}") as it would be caught using except Exception: regardless?

Otherwise I think this custom exception definition should be moved outside of the non-public method, so that it can more easily be imported if an user wants to catch it.

As discussed in the meeting earlier today, I will work on this
