Feature Request: Signal Processing/Filtering Blocks

Hi there,

I am currently developing a robotics project and I've found your interface for communication very useful. I am considering adding signal processing blocks to the workflow and would like to hear your thoughts on incorporating filters such as:

• Low-pass and High-pass filters
• Moving Average
• Kalman Filter (potentially)

I have already set up my local environment to work with the source code and I am planning to implement these features. I would appreciate any feedback or guidance on how you'd like these to be integrated into the current architecture before I start working on a Pull Request.

Best regards,
