changed hardcoded crs to parametric in most scripts

[aburianne]

Three files requires specific attention from reviewer :

• [ ] data/spatial/iris.py : changed from constant to parametric crs value, but this is a specific file in context so maybe back to constat?
• [ ] matsim/scenario/supply/gtfs.py : doesn't support numerical EPSG code (2154), requires litteral ("EPSG:2154") instead
• [ ] matsim/scenario/supply/osm.py : tricky insert of numerical to string parameter in string chain already strongly formated

about CRS formatting, i proposes simple integer numerical value, compatible with : https://pyproj4.github.io/pyproj/stable/api/crs/crs.html#pyproj.crs.CRS.from_user_input

I forced to crs with espg parameters, but even when reverse to initial str constant it differs un hash code. Data seams correct, any idea?

Let's keep it fixed in this repository and update it on a case-by-case basis, at least for now.
