Python package "six" required

[tobytes]

Operation system: Ubuntu 24.04
Python version: 3.12.3
Weewx version: 5.1.0-4 installed via apt package

I tried to install the extension as described in the installation instruction on a fresh weewx installation.
weectl extension install https://github.com/gjr80/weewx-gw1000/releases/latest/download/gw1000.zip

Current behavior:
I got the following error:

Using configuration file /etc/weewx/weewx.conf
Install extension 'https://github.com/gjr80/weewx-gw1000/releases/latest/download/gw1000.zip' (y/n)? y

    __import__('install')
  File "/tmp/tmp85zgwas9/gw1000/install.py", line 59, in <module>
ModuleNotFoundError: No module named 'six'

During handling of the above exception, another exception occurred:

    raise ExtensionError("Cannot find 'install' module in %s" % extension_installer_dir)
weecfg.ExtensionError: Cannot find 'install' module in /tmp/tmp85zgwas9/gw1000/

Expected behavior:
It seems the library "six" is a requirement to install the extension.
It would be helpful to have this mentioned in the installation instruction.

Solution:
Install library six:
e.g. apt install python3-six

Thank you for the hard work!
