Ignore constant factors when applying SIRUS

[ConnectedSystems]

Leads to an error about _rules!() keyword parameter not being defined in cases where non-constant factors are provided to SIRUS.

Ignoring constant factors resolves the issue, and probably should be done as part of cluster_rules()

fields_iv = ADRIA.component_params(rs_all, [Intervention, CriteriaWeights]).fieldname
varying_factor_idx = .!rs_all.model_spec.is_constant
varying_factor_names = rs_all.model_spec.fieldname[varying_factor_idx]
 
foi_idx = map(x -> x ∈ varying_factor_names, fields_iv)
fields_iv = fields_iv[foi_idx]
 
scenarios_iv = all_scens[:, fields_iv]
 
n_clusters = 4
clusters = ADRIA.analysis.cluster_scenarios(stac, n_clusters)
target_clusters = ADRIA.analysis.target_clusters(clusters, stac)
 
max_rules = 4
rules_iv = ADRIA.analysis.cluster_rules(target_clusters, scenarios_iv, max_rules)
 
rules_scatter_fig = ADRIA.viz.rules_scatter(
    rs_all,
    scenarios_iv,
    target_clusters,
    rules_iv;
    fig_opts=Dict(:size=>(1000, 800))
