Duplicate area code in mappings.py leading to bugs

[morrisonmaxw]

Area code 10Y1001A1001A82H is used for both DE_LU and LU_BZN. It looks like only DE_LU is valid? Entsoe Areas Ref

This is leading to unexpected results in data processing.

One example is I am looping through country codes for EntsoePandasClient.query_day_ahead_prices and get a duplicate result for DE_LU and LU_BZN.

Another example is I am extracting mappings.py into JSON to build my data model and LU_BZN gets omitted:

`import json
from entsoe import mappings

area = mappings.Area
psrtype = mappings.PSRTYPE_MAPPINGS
docstatus = mappings.DOCSTATUS
bsntype = mappings.BSNTYPE
marketagreementtype = mappings.MARKETAGREEMENTTYPE
documenttype = mappings.DOCUMENTTYPE
processtype = mappings.PROCESSTYPE
neighbours = mappings.NEIGHBOURS

def enum_to_json(enum_class):
members = []
for member in enum_class:
print(member) # Debugging line
members.append({
"area_key": member.name,
"code": member.code,
"meaning": member.meaning,
"timezone": member.tz
})
return members

data = {
"areas": enum_to_json(area),
"psrtype": psrtype,
"docstatus": docstatus,
"bsntype": bsntype,
"marketingagreementtype": marketagreementtype,
"documenttype": documenttype,
"process_types": processtype,
"neighbours": neighbours
}

json_output = json.dumps(data, indent=4)

with open('entsoe_mappings.json', 'w') as file:
file.write(json_output)`
