Feature request - refactor example notebooks so all parameters are automatically findable

[GFleishman]

Many current bigstream users are working with Jupyter notebooks given to them by Greg (me). Parameters for various steps in their registration pipeline are defined throughout the notebook. First, an updated standard notebook would be very valuable. Second formatting all parameters in such a way that they can easily be dumped into a json or yaml file would help interface with automated tools that want to wrap or call bigstream, like NextFlow.

Would be great to add a use of https://docs.sweep.dev/blogs/file-cache or lru_cache so to no repeat the same params. Thanks
