This PR implements the data APIs that recover the fixed and random effect matrices and vectors from a @formula macro.
I tried to make it from scratch but I was overwhelmed by the macro obscure magic necessary.
So I resorted to having StatsModels.jl and MixedModels.jl as dependencies for parsing the formula thing and using some of the scaffolding inner functions to get access to the underlying data.
I also added GLM.jl since the Likelihood structs for likelihood families and link functions will come in handy for the next PR: likelihood functions.
