Files of premises and parcels of legal persons (unified version)

Resumption of DGFIP data on parcels and premises of legal persons ([source](https://www.data.gouv.fr/datasets/files-des-localaux-et-des-parcelles-des-persons-morales/)), unified in a single file for the whole of France** in a usable format without prior download (parquet) with standardisation of columns to facilitate use. #### Changes to DGFIP files * standardizes data structures between the 2019-2023 and 2024-2025 vintages * adding an insee code to facilitate filters and joins * explicit and homogeneous field names between plots and premises * division into separate columns of concatenating fields of several pieces of information (code, wording, exemption code) * addition of labels only present in the documentation * Removal of white spaces at the beginning and end of the line * removal of string handling residues ('mon\_texte' or ''mon\_texte'' instead of my\_texte * removal of seizure residues * the cleaning pass on denominations is made on the most common errors, I encourage you to use text search functions (FTS, soundex, tokenization, etc.) and avoid ILIKE and CONTAINS
