setup.sh: argparse wheel necessary?

[rzbrk]

According to George B. from RPF, argparse has been included in the Python standard library since Python 3.2 so I was curious why an argparse wheel is necessary.
Version 1.4 seems to date from 2015. It won't affect other Astro Pi operations since the module is only installed for the calliope user but it looks unnecessary.

Argparse is installed on AstroPi-IR. I checked it with import argparse in the Python console:

pi@astropiir:~/src/CalliopEO_AstroPi $ python3
Python 3.7.3 (default, Jan 22 2021, 20:04:44)
[GCC 8.3.0] on linux
Type "help", "copyright", "credits" or "license" for more information.
>>> import argparse
>>> argparse.__version__
'1.1'
>>>
