Generate random fields.

Example: generate random vector for DM (problem) from simple interface, where FIELD random values of DOFs are in range from -1 to 1, and FIELD2 random values are in range from 0 to 1.

auto x = opt->setRandomFields(simple->getDM(),
{{"FIELD1", {-1, 1}}, {"FIELD2", {0,1}}});

TODO: Set random field to specific entities, and potentially order for testing proposes to dissect error in tangent matrix.

Parameters
