feat: implement trigger for resolution

[dominiklaux]

This adds a trigger implementation to change the simulation resolution (perimeterResolution, spatialIncrement) during a simulation.

Well done @dominiklaux :)

What if arg is not a float?
Maybe we can add somehting like:

 bool valid = true;
    if (newPerimRes != FLOATERROR) {
        if (newPerimRes <= 0.0 || newPerimRes > 10000.0 || std::isnan(newPerimRes)) {
            cout << "Error: perimeterResolution must be between 0 and 10,000." << endl;
            valid = false;
        }
    }
    if (newSpatialInc != FLOATERROR) {
        if (newSpatialInc <= 0.0 || newSpatialInc > 10000.0 || std::isnan(newSpatialInc)) {
            cout << "Error: spatialIncrement must be between 0 and 10,000." << endl;
            valid = false;
        }
    }

    if (!valid) return error;

Thanks!
if arg is not a float, the getFloat() will return FLOATERROR, so this should be covered!
I added a check to ensure >= 0.0, but would rather avoid to set an upper limit to keep it simple?

Thanks for taking in consideration my review :)
Its a go for me, well done.
