Subject: [PATCH] Don't index all fields by default

The code was setting an index on every field by default.
This meant that a simple model like:

```python
class Foo(SQLModel, table=True):
    a: str
    b: int
    c: str
```
Would have indices for all fields. This is wrong, the default should be to not create an index.
