This continues the work for `printf` support from from tthe issue
https://github.com/tursodatabase/turso/issues/885.
This PR adds support for `%i` operands in the printf function. An
example of a command that works now and didn't before:
```sql
SELECT PRINTF("Decimals: %d %i", 200, 300);
```
This is Just an initial very simple contribution to get my feet wet and
learn the basics about the project and how contributions here work. I
intend to do something more meaningful in next contributions. Probably
will try to finish support for missing `printf` functionality also.
Closes#2615
