When using LEAN CLI in live mode with your broker, e.g. IBKR, one has to choose a real time data feed from a list of data feeds:

```
Select a data feed:

1) Interactive Brokers
2) Tradier

13) Polygon Data Feed
14) Custom data only
```
Is it possible to add Tiingo to this list? Or can we do it ourself? Can you share some pointers?
 I believe Tiingo is used by QC too so this should be definitely possible.
