How to define the optimizer and define the LR scheduler in the current version of swyft?

[Haowen-Zhong]

I’m new to swyft and would like to use it for likelihood-free parameter estimation in my research. While reproducing several example notebooks, I noticed they reference swyft.OptimizerInit, which I can’t find in the current API. What’s the recommended way to initialize the optimizer (and scheduler) now?
