Various improvements:
- Make promise API the default for `@tursodatabase/turso`
- Add a compatibility test suite for database, serverless, and better-
sqlite3
- Improve serverless driver a bit to be more compatible.
Closes#2322
We need to use sequence requests to handle multiple SQL statements for exec():
```
DatabaseError {
message: 'SQL string contains more than one statement',
}
```
```

This package is for serverless access to the Turso Cloud using SQL over
HTTP protocol. The purpose of this package is to provide the same
interface as `@tursodatabase/turso`, but for serverless environments
that cannot host the database engine.
The package also provides a `@libsql/client` compatibility layer in the
`@tursodatabase/serverless/compat` module for drop-in replacement for
existing clients.
