Python version
3.9

Current behavior (bug description)
When calling both the .encode and .decode function with any birthplace it raises a ValueError:
Traceback (most recent call last):
File "/Users/davideramondetti/..../handler.py", line 19, in
cod1 = codicefiscale.decode(
File "/Users/davideramondetti/.../venv/lib/python3.9/site-packages/codicefiscale/codicefiscale.py", line 485, in decode
raise ValueError(f"[codicefiscale] wrong birthplace code: {birthplace_code!r}")
ValueError: [codicefiscale] wrong birthplace code: 'L219'

Expected behavior
It is expected for the .decode to return the extracted data, and for the Encode to output the fiscal code.
