New dates_normalizer pipe to parse the ml dates value & format

[percevalw]

Description

To address #10. This is closely related to https://github.com/aphp/edsnlp/issues/174, but here we assume that the date has been correctly extracted, whereas eds.dates has to find a balance between precision and recall, limiting the variety of date formats it supports.
