The ABM's RNG is not used after initialization

[reneSchm]

Bug description

The RNG in the Model is only used to initialize each Person with a key, index and counter, but afterwards it is entirely unused.

Current intended behaviour is that changes to Model RNG is relevant to simulation results.

Version

Any

To reproduce

1. Create ABM, add persons, locations, ...
2. Change seeds of Model.get_rng()
3. Simulate
4. Observe no changes (compared to old seed)

Relevant log output

Add any relevant information, e.g. used compiler, screenshots.

Possible fix:
Change PersonalRandomNumberGenerator constructor so that it takes index and counter from Person, and key from Model::m_rng. Check all construction sites.

We may be able to remove Person::m_rng_index, as it is always the same value as person_id.
