Allow setting source address

[hadleyrich]

I needed to set the source address to broadcast on a specific interface. This allowed me to do so, not sure if it's of use to anyone else but I thought I'd contribute in case you wanted it :)

Summary by CodeRabbit

• New Feature: Added the ability to specify a source_address in the StupidArtnet class. This allows users to define a specific network interface for sending Art-Net packets, providing greater control over packet routing. The socket option SO_REUSEADDR is set when a source address is provided, enabling the reuse of socket addresses.

Hey @hadleyrich, really good work, and thank you for making the PR

It looks like I might need to upgrade the python version in CI to see the tests, meanwhile would you mind offering a small description of the feature either in code or in the readme?

Can you also rebase master so that the test suite can run?

Walkthrough

The change introduces a new source_address parameter to the StupidArtnet class's initializer. This allows clients to specify a network interface for sending Art-Net packets by setting the SO_REUSEADDR socket option and binding the socket to the provided address.

Changes

File	Summary
stupidArtnet/StupidArtnet.py	Introduced a source_address parameter to the __init__ method of the StupidArtnet class. If provided, the socket binds to this address, enabling the use of a specific network interface for sending Art-Net packets.

In the land of code, changes are afoot,

A rabbit hops, leaving tracks in the soot.

With a tweak here, and a tweak there,

The packets find their way, through the digital air.

So raise your carrots high, let's give a cheer,

For the code is clear, and the path is near! 🥕🎉

• 22-23: The function signature of __init__ has been changed to include a new parameter source_address. Ensure that all calls to this function throughout the codebase have been updated to match the new signature. Also, verify if the default value of None for source_address is appropriate in all use cases.

• 60-63: The socket option SO_REUSEADDR is set and the socket is bound to the source address if it is provided. This allows the client to use a specific network interface for sending Art-Net packets. However, be aware that setting SO_REUSEADDR can potentially lead to some security risks as it allows multiple sockets on the same host to bind to the same IP address and port. Make sure you understand the implications of this change and consider whether it's necessary in your context.
