KeyError 'currencyCode' in get_financial_data()

**Describe the bug**
`get_financial_data()` is crashing

**To Reproduce**
Steps to reproduce the behavior:
```python
import yahooquery as yq

aapl = yq.Ticker('aapl')
aapl.get_financial_data(
frequency='a',
types=['PeRatio', 'PegRatio', 'PsRatio', 'PbRatio']
)
```

**Expected behavior**
I expect the function to return a pandas Dataframe with those values

**Screenshots**

1041 in_axis, level, gpr = False, gpr, None
1042 else:
-> 1043 raise KeyError(gpr)
1044 elif isinstance(gpr, Grouper) and gpr.key is not None:
1045 # Add key to exclusions
1046 exclusions.add(gpr.key)

KeyError: 'currencyCode'
```
