I2C io interface

Hi Gerard,

Thank you for your work on this.

Due to the open source nature of SIP and the plugins I consider it to always be in a sort of beta test. If a user finds a bug they will usually report it here or raise an issue on GhiHub.

I think we could just add your plugin to the SIP plugins repository and announce it here and on the SIP GitHub repository in the Discussions section:
https://github.com/Dan-in-CA/SIP/discussions

I would also like to add a reference to your plugin on the SIP documentation wiki if that is OK with you.

I have cloned your plugin to my test Pi and will do some testing and then see about posting it to the plugin repo on GitHub.

One thing that might be helpful for users might be to rename the plugin to something a bit more descriptive of what it does such as i2c_port_expander. The chip name is kind of obscure to someone like me who is not as familiar with electronic components as you are.

As far as adding custom plugin repositories to SIP, I think that is possible. It would require some changes to SIP's plugin manager which is itself a plugin.
