Entsoe imbalance prices

[seeeme]

I’m not sure if this qualifies as an issue, but it may require upgraded functionality.
The ENTSO-E API returns a maximum of 10 days of data per API call.
For longer periods, iteration has to be implemented manually.
Maybe this could be handled in the background inside the "query_imbalance_prices" method.

The same thing occurs when querying for actual generation and load. It does not seem to be the case for day ahead prices

It looks like entsoe changed some limits behind the scenes. Consider this query for Actual Generation Per GenerationUnit for France for only one day (202511250000 - 202511250000):

❯ curl --location "https://web-api.tp.entsoe.eu/api?documentType=A73&processType=A16&in_Domain=10YFR-RTE------C&periodStart=202511240000&periodEnd=202511250000&securityToken=${ENTSOE_API}"

The response we get is:

<?xml version="1.0" encoding="UTF-8"?>

Edit: I reported this to ENTSOE. I'll update as I receive an answer.
