Description

# 🐜 Bug Report
In `command_parse` there is a line declaring `target_obj=self` which creates a reference to `self`

https://github.com/MetOffice/ANTS/blob/70dbeb2d3c802076bfd3d4d61cb6d4f6f381044e/lib/ants/command_parse.py#L92

Later arguments are added depending on if `target_obj is self` which always evaluates to True. It would be simpler to change the requirements of arguments to `True`.

## How to reproduce
Step by step guide to reproduce the behaviour:

1. `target_obj` assigned to `self`
2. `target_obj` is never re-assigned or copied in any execution path

## Environment
I am using the ANTS 3.2.0 environment.

## Version
This bug exists in ANTS 3.2.0/head of main

Research direction

Start in lib/ants/command_parse.py at the command_parse entry point and line 92, then trace how target_obj is used when arguments are added. Confirm the conditional does not depend on a value that cannot change, and verify that command parsing still adds the expected arguments.
