pinging @thazhemadam and @ChrisRackauckas to see if workflows and docs are going in the right direction.

The idea here is to split some ReservoirComputing models into their own packages with standalone installation and documentation. The first of these packages is ReservoirCellularAutomata, since these architectures are already in ReservoirComputing. These packages should live in lib, and have their own tests/docs/version. The idea is to expand these in the future and have ReservoirComputingBase, LiquidStateMachines etc...

Essentially, I am going for something similar to GraphNeuralNetworks.jl, with a multi lib repo, but with a structure that resembles Lux.jl's, that keeps the additional libraries under lib

gentle ping for this

It's just 1 dep, right? Any reason this shouldn't just be an extension?

It's just one dependency, but the reasoning behind splitting in a new package is that ReservoirCellularAutomata exports new models and methods, not just simple dispatches

adding this to ext

closing this, cleaner version on #299
