Allow the semantic data provider to return semantizer objects

Instead of returning "anonymous" objects, we could add an option to the semantic data provider to return objects defined according to the https://github.com/assemblee-virtuelle/semantizer-typescript library developed by @lecoqlibre.

This would give us greater control over the data we receive.

Locate the semantic data provider and review how it currently returns anonymous objects. Read the semantizer-typescript library linked in the issue and determine how an opt-in return mode should expose semantizer objects; the work is done when the provider can return those objects without changing the default behavior.
