--- BEGIN ISSUE ---
Specifying 3.7+ in setup.py
sqlglot fails with Python version < 3.7. 

While Python 3.6 is end-of-life, there are systems that still use 3.6 as they transition to 3.7. Having either `setup.py` or `setup.cfg` specify 3.7+ or adding to README would be helpful. 

```
import sqlglot
```
`SyntaxError: future feature annotations is not defined`
