feat: Add a named model for Molineaux model.

[b-s-code]

Problem

When a user wants to use the Molineaux model, they must somehow obtain a parameterisation of it and a list of appropriate model options.

The problem this PR solves is eliminating the need to track down such model options and parameter values in order to use the Molineaux model.

It's hoped this will improve reproducibility and save on communication, by making clear the provenance of the values used.

Solution

In #419, the ability to hardcode a collection of model options and parameter values, identifiable by some string name was added.

Thus users can use a pre-defined collection of model options and parameter values, if they reference that collection by name in their scenario. This PR adds such a collection of values under the name molineaux_original.

A user can select this pre-defined collection of model options/parameters by specifying the value molineaux_original for the name attribute on the <ModelName> tag:

    <model>
        <ModelName name="molineaux_original"/>
        <!-- <ModelOptions> node not required unless overriding some value. -->
        ...
        <!-- <parameters> node not required unless overriding some value. -->
   </model>

The collection of model options and values being added is consistent with those values found in the papers/accompanying workflow code referenced below.

Points of note:

• Some model options are not hardcoded since doing so would now be redundant (see ModelOptions.cpp comments for details).
• There are some values that need to be specified in the scenario XML in order to use the Molineaux model, which are not packaged up with the "molineaux_original" in this PR. In particular <weight> under <human> under <model>. TODO : is that all?
• TODO : consider HEALTH_SYSTEM_MEMORY_FIX... would have been on (implicitly) in original scenarios. But it's not here...

Testing

Added one new test to cover the newly added combination of ModelName/Parameters/ModelOptions.

All existing tests continue to pass.
