Euro Short-Term Rate.

The euro short-term rate (€STR) reflects the wholesale euro unsecured overnight borrowing costs of banks located in
the euro area. The €STR is published on each TARGET2 business day based on transactions conducted and settled on
the previous TARGET2 business day (the reporting date “T”) with a maturity date of T+1 which are deemed to have been
executed at arm’s length and thus reflect market rates in an unbiased way.

```python wordwrap
obb.fixedincome.rate.estr(start_date: Union[date, str] = None, end_date: Union[date, str] = None, provider: Literal[str] = fred)
```
