This adds a `turso_assert` macro that is Antithesis aware when
`antithesis` feature flag is enabled. I did not yet convert any
call-sites to use it.

Makes it easier to test the feature:
```
$ cargo run -- --experimental-indexes
Limbo v0.0.22
Enter ".help" for usage hints.
Connected to a transient in-memory database.
Use ".open FILENAME" to reopen on a persistent database
limbo> CREATE TABLE t(x);
limbo> CREATE INDEX t_idx ON t(x);
limbo> DROP INDEX t_idx;
```
This implements libSQL compatible Rust API on top of Limbo's core. The
purpose of this is to allow libraries and apps that build on libSQL to
use Limbo.
