Special Trust Region Algorithm for NLLS Problems with bound constraints.

Describe the solution you’d like

See https://nmayorov.wordpress.com/2015/06/19/trust-region-reflective-algorithm/ for a description of the algorithm.

Additional context

First, we need to add bound constraints to the NLLS Problem in SciMLBase
