Can we check for point identification before checking for LP/QP packages? #233

Example:

library("ivmte")

ivmte(data = AE,
      outcome ~ worked,
      propensity = morekids ~ samesex,
      target = "att",
      m0 = ~ u,
      m1 = ~ u)

If Gurobi is installed, this works fine. But Gurobi is not needed for this, since it's point identified. If Gurobi is not installed, I get this error:

Error: A direct regression via quadratic programming may only be peformed if the solver is Gurobi or MOSEK. Please install either solver and set 'solver = "gurobi"' or 'solver = "rmosek"'.

I think we want people to be able to use ivmte for point identified cases without having to have a solver installed.

Ah sorry, I thought I had taken care of this in the past. I must have undone it or misremembered. It should now be fixed!
