Submodels take kwargs variable splits rather than NamedTuples.

[SamuelBrand1]

Goal

This PR is aimed at addressing the problem outlines in #63 .

API changes

None at top level API (e.g. running this script.

Where NamedTuples are used at lower level we can splat their fields as kwargs e.g.

Rt-without-renewal/EpiAware/src/models.jl

Lines 17 to 26 in 8035d60

	#Predictive distribution of ascerted cases
	@submodel generated_y_t, generated_y_t_aux = observation_process_obj.observation_model(
	y_t,
	I_t,
	epimodel::AbstractEpiModel;
	pos_shift = pos_shift,
	observation_process_obj.observation_model_priors...
	)

Closes #63

I've just had a thought that I'm using a postfix of _dist in some places and _prior in others to indicate the prior/generative distribution of parameters... We should choose one and go with that (happy for this to become a new issue).
