Make neural mass housekeeping PR non-breaking

[MasonProtter]

This is a PR that is targeting #530, rather than a commit to that branch because I want to see what people think of this. This is an idea I had to make that PR non-breaking.

Basically, instead of having two separate types for noisy versus non-noisy, this PR puts them together into one type, but they differ by a type parameter, e.g.

julia> typeof(KuramotoOscillator(;name=:n, include_noise=true))
KuramotoOscillator{Neuroblox.Noisy}

julia> typeof(KuramotoOscillator(;name=:n, include_noise=false))
KuramotoOscillator{Neuroblox.NonNoisy}

I also changed the keyword argument back to include_noise rather than noise, since that is what current Neuroblox master uses.

Any thoughts or feelings on this approach?

I prefer this, tidier type tree, as in theory we could apply it to all atomic Blox.

Oh yeah I think this is much better. Seems easily extended to have delay types as well, and avoids the messiness of those constructor functions.

Great, I'll merge it into your PR then.
