update_parms: Adjust termination criteria for while loop in IR

updateparms(; Cr=Crdefault, Ce=Cedefault, Rmax=Rmaxdefault, litmax=litmax_default)

C. T. Kelley 2025

Update the termination parameters in MultiPrecisionArrays.

This creates a new TERM data structure that you send to the solver as a kwarg.

This changes the values of the parameters. I do not recommend that you mess with this unless you have a good reason. One such reason might be that the default limit on the number of iterations (10) is not working for you.

I start with the default values, so unless you specify otherwise, any parameter will take its default value.

We store the parameters in a mutable structure TERM

mutable struct TERM
       Cr::Real
       Ce::Real
       Rmax::Real
       litmax::Int
end

and that is passed to the solvers. So, if AF is a multiprecision you use the optional argument term_parms.
