broken with python 3.13 as pipes module got removed

Description:

Running the curses frontend doesn't work with python 3.13 as it uses the pipes module which got removed.

Additional info:

• extra/canto-curses 0.9.9-7
• https://github.com/themoken/canto-curses/issues/57

Steps to reproduce:

1. $ canto-curses

$ canto-curses 
Traceback (most recent call last):
  File "/usr/bin/canto-curses", line 3, in <module>
    from canto_curses.main import CantoCurses
  File "/usr/lib/python3.13/site-packages/canto_curses/main.py", line 18, in <module>
    from .gui import CantoCursesGui, GraphicalLog
  File "/usr/lib/python3.13/site-packages/canto_curses/gui.py", line 16, in <module>
    from .command import CommandHandler, cmd_execute, register_command, register_alias
  File "/usr/lib/python3.13/site-packages/canto_curses/command.py", line 17, in <module>
    import pipes
ModuleNotFoundError: No module named 'pipes'

Solution?

Although my python isn't very strong, I didn't see any usage of the pipes module itself
https://github.com/themoken/canto-curses/blob/master/canto_curses/command.py Just the import.
Therefore I simply tried the following patch:

--- a/canto-curses/canto_curses/command.py
+++ b/canto-curses/canto_curses/command.py
@@ -14,7 +14,6 @@
 import logging
 import curses
 import shlex
-import pipes
 
 import readline
 

And the curses interface starts again. Tried simple testing if I can still read feed entries or open them in a browser. And that works.
Can create a MR, but as I'm unsure if I didn't overlook something, I want some more eyes on this if possible.
