Add support for Seatalk1 on Raspberry Pi 5

[astuder]

As discussed in issue #1658 the existing integration of Seatalk1 does not work for Raspberry Pi 5 as the underlying Python library doesn't support the Raspberry Pi 5.

This pull-request uses the gpiod Python library to implement the functionality. This library is also supported by older versions of Raspberry Pi OS and hardware, so it could eventually replace pigpio.

I added a new field GPIO Library to the connection dialog to select between gpiod and pigpio.

I tested this pull request on a Raspberry Pi 5.

The standalone Python script (available here) was successfully tested on Raspberry Pi 3, 4 and 5, running Raspberry Pi OS Bookworm and Bullseye.

I think the approach is sound and not being a Pythonist nor a Seatalk user I don't have much to comment on here.

Let's try to get the doc update in 4664938 included in this PR, makes for a little nicer Release Notes.
